The Joy Luck Club Essays (1072 words) - Chinatown, San Francisco
The Joy Luck Club The Joy Luck Club By Amy Tan Is it reasonable for judge somebody by their sex? In customary Chinese culture, numerous decisions were made about an individual just by watching their sex. The lady was looked upon as a sub-par being. They had almost no status in the public arena, and little was normal from them. They were oppressed when they attempted to go to bat for themselves. Chinese culture was usually male overwhelmed. The male was relied upon to do the greater part of the work, and the lady was required to remain at home with their mouth shut. This custom leaves an unwanted inclination in a lady's heart. They feel like nobody cares, and it makes it a lot harder to live with an idealistic view on life. In the novel, The Joy Luck Club, by Amy Tan, surveys the lives of three Chinese ladies, Ann-Mei Hsu, Lindo Jong, what's more, Ying St. Clair. These ladies experience childhood in customary Chinese homes, where there is sexism. They manage major issues that degenerate their lives. Through persistence and the progression of time their lives come back to ordinary. Ann-Mei, Lindo, and Ying are enslaved by guys on account of their sex, and Chinese custom. Ann-Mei was abused from numerous points of view. Her mom was welcome to invest energy at the home of a well off trader named Wu Tsing. Around evening time he would come into Ann-Mei's mom's room and assault her. In spite of sincerely startling Ann-Mei this shows the absence of regard for a ladies in China. Ann-Mei's mom is constrained into concubinage in light of her absence of intensity as a ladies. She turns into the third spouse. As a third spouse she keeps up almost no status in the home of Wu Tsing. Ann-Mei's family repudiates her mom on the grounds that by turning into a third spouse she has carried disgrace to her family. ?At the point when I was a little youngster in China, my grandma revealed to me my mom was a apparition?. Ann-Mei is educated to overlook concerning her mom and proceed onward in her life. The way that Ann-Mei is advised to overlook her mom since she has become something she proved unable control, is ludicrous. She was assaulted and constrained into concubinage. The absence of thankfulness for a female causes this sentiment of disgrace for the Mei family. Since assault and polygamy is acknowledged in China, it causes it to give the idea that what Ann-Mei's mom has done is wrong, and what Wu Tsing did was correct and ordinary. Ann-Mei's little girl Rose, harvests the disservices of being a lady since she feels that she can't decide. ?...Ted chosen where we took some time off. He chose what new furniture we ought to buy...We used to talk about a portion of these issues, however we both realized the inquiry would come down to my platitude, ?Ted, you choose.'? This shows Rose's incapacity to be self-assured, and her reliance on a male. The life of Ann-Mei exhibited how ladies were underestimated in the public arena. The narrative of Lindo Jong allegorizes how ladies were oppressed. At the exceptionally youthful age of twelve, Lindo is pledged to Tyan-yu. This is a case of the irrelevance of a female's emotions. No one needs to have a masterminded marriage. Marriage is hallowed, and should be practiced by two individuals who are infatuated with one another. This is a demonstration of extraordinary shamefulness to Lindo. This shows how an acknowledged Chinese practice is in fact terrible toward the female sex. ?I [Lindo] once yielded my life to keep my folks' guarantee?. Here, Lindo is discussing her masterminded, cold marriage. Chinese custom is confining Lindo from being her own individual, and living her own life. She can't settle on her own choices. Lindo is so ready to forfeit her life so as to protect the respect of her folks. There is no respect in compelling somebody to be troubled. On another note, Lindo was immediately accused for not having youngsters. As a matter of fact, their absence of posterity came about because of Tyan-yu's absence of communication with Lindo. It was incomprehensible for Lindo to go to bat for herself in light of the fact that regardless, the male would be accepted over the female. Lindo is an ideal case of how Chinese custom disallowed the female

[00:04:54] If you use the Corson technique you are strengthening your critical thinking skills. It also has lots of other benefits too. For one your professor is going to be super happy that you are not running to them every five seconds with a new question. You wont be saving the professors time and you will help them to understand the exact context of the problem with your question.

A Silent Death Elie Wiesels Night - 614 Words
ââ¬Å"A silent death, suffocation. No way to scream, to call for helpâ⬠( Wiesel 94). Elie Wiesel and many other Jews were put in freight cars and and thought that their lives were over. The jews couldnââ¬â¢t have anyone help them, even when they were calling out for help. Elie wrote a novel called Night, he wrote from his own experience that he had when he was a child. He thought that once he got out of the freight car that it would be the end of the road. At the concentration camps jews could not talk, they had to do everything that Hitlerââ¬â¢s men said. While the Holocaust was going on Jews were changing their emotions and how they were acting and working in the camps. When Jews were in the concentration camps they worked non-stop, the Nazis pushed them to keep working hard. The Jews were beaten badly and they got very little food to eat or clothes to wear. If Jews did not do what they were told or talk when not suppose to the Nazis would find a way to punish them. When the Jews were being punished others would not stand up for each other they just stood there silent which gave the Nazis more control over them. ââ¬Å"... he slapped my father with such force that he fell down and then crawled back to his place on all foursâ⬠(Wiesel ,39).

Critique of The Stanford Prison Experiment Essay - 757 Words
Critique of The Stanford Prison Experiment The Stanford Prison Experiment of 1973 raises troubling questions about the ability of individuals to exist repressive or obedient roles, if the social setting requires these roles. Philip K. Zimbardo, professor of Psychology at Stanford University, began researching how prisoners and guards assume submissive and authoritarian roles. He set out to do this by placing advertisements in a local newspaper, stating that male college students would be needed for a study of prison life paying fifteen dollars per day for one to two days. Of the seventy-five responses, twenty-one were selected, half of them as guards (Zimbardo p. 364) and the other half as prisoners. (Zimbardo p. 364) Philipâ⬠¦show more contentâ⬠¦In the mock prison, inverse psychological relationships developed between prisoners and guards. Prisoners began to feel that there was no way to beat the system. They felt that it is better to do nothing, except what the guards told them. They didnt want, act, or feel anythin g so they wouldnt get in trouble. Guards, on the other hand, assumed authority roles to control the prisoners and keep the prison in order. Some of the guards reacted extremely, and behaved with hostility and cruelty towards the prisoners. Others, however, were kinder, and occasionally did favors for the prisoners and didnt punish them as much. On the morning of the second day of the experiment, the prisoners broke out in a rebellion. They barricaded themselves in their cells by pushing their cots up against the cell doors; they also proceeded to curse and jeer at the prison guards. The guards regained control of the prison by spraying fire extinguishers on the prisoners and stripping them of their clothing. The guards also forced the leaders of the riot into solitary confinement. Following the riot, the prisoners were more compliant to the rules the guards laid out for them. There was never another united uprising by the prisoners against their authority figures, the guards. After the prisoners had accepted andShow MoreRelatedCritique the Power of Organizations from Weberian and Goffmanesque Perspective in the Stanford Prison Experiment1780 Words à |à 8 PagesQ 1.

Using Waste Cooking Oil as Feedstock and Candida Antarctica Free Essays
Production of Biodiesel by Enzymatic Transesterification: using Waste Cooking Oil as feedstock and Candida Antarctica Lipase B as Biocatalyst. CHAPTER 1 INTRODUCTON The high cost of bio-diesel, compared to petroleum-based diesel, is a major barrier to its commercialization. It has been reported that 60-90% of bio-diesel cost arises from the cost of the feedstock oil (C. We will write a custom essay sample on Using Waste Cooking Oil as Feedstock and Candida Antarctica or any similar topic only for you Order Now C. Lai et al. , 2005). Studies showed the potential of waste-cooking oil (WCO) as a material for biodiesel production (Sulaiman Al-Zuhair, 2008). Therefore, the use of WCO should greatly reduce the cost of bio-diesel. In addition to the choice of lipase employed, factors which make the transesterification process feasible and ready for commercialization are: enzyme modification, the selection of feedstock and alcohol, use of common solvents, pretreatment of the lipase , alcohol to oil molar ratio, water activity/content and reaction temperature. Optimization of these parameters is necessary in order to reduce the cost of biodiesel production. Use of no/low cost waste materials such as the WCO will have double environmental benefits by reducing the environmental pollution potential of the wastes and producing an environmentally friendly fuel. In addition, production of bio-diesel from WCO is considered an important step in reducing and recycling waste. A fresh vegetable oil and its waste differ significantly in water and free fatty acids (FFAs) contents, which are around 2000 ppm and 10-15%, respectively (C. C. Lai et al. , 2005; Y. Zhang et al. , 2003). Because of this the traditional alkaline-catalyzed biodiesel production is unsuitable (Zhang et al. 2003). The use of the enzyme lipase as a biocatalyst for the transesterification reaction step in biodiesel production has been extensively investigated. Lipase is produced by all living organisms and can be used intracellularly or extracellularly. In order to design an economically and environmentally sustainable biodiesel production process, a proper understanding of the f actors affecting the process and their relative importance of enzyme-catalyzed biodiesel production is necessary. A general equation for transesterification (where group R is a fatty acid, Rââ¬â¢ is the ength of the acyl acceptor and Râ⬠is the rest of the triglyercide molecule) is as follows: Methanol is the most popular alcohol used in the transesterification process because of its relatively cheaper price compared to other alcohols. When methanol is used in the process, the reaction is known as methanolysis as shown in the following equation: Lipases from microorganisms (bacterial and fungal) are the most used as biocatalysts in biotechnological applications and organic chemistry. Fungal ââ¬â source lipases have been found to produce high yields of lipases compare to the animal and plants. Because their bulk production is easier, commercialization of microbial lipases and their involvement in enzymatic biodiesel production are more common than animal and plant ones (Hasan et al. , 2006;Akoh et al. , 2007; Antczak et al. , 2009). The lipase to be employed as the biocatalyst is Candida Antarctica lipase B (Novozyme CABL L), one of the most common fungal lipase used for the production of biodiesel (Vasudevan and Briggs, 2008). Lipases are capable of converting all the triglycerides derive from the feed stocks into their respective fatty acids methyl esters (FAMEs). They act on the ester bonds of carboxylic acids allowing them to carry out their primary reaction of hydrolyzing fats (Joseph et al. , 2008). Enzyme immobilization is an important approach that could be used as a tool to improve and optimize operation stability, activity and selectivity which allows the enzyme to study under harsher environmental condition and also provides their separation from the reaction mixture without filtration in case of packed bed reactor (Fernandez-Lafuente et al. , 1998; Bhushan et al. , 2009; Gao et al. 2006) and, hence, could lead to more favorable economical benefits. The cost of lipase makes up 90% of the total cost of enzymatic biodiesel production. A significant portion of that is associated with the use of expensive carrier or support materials (Dizge et al. , 2009a). Search for cheaper support materials has been ongoing in order to reduce the overall cost of enzymatic biodiesel production (Robles et al. , 2009). Thus it is important to immobilize l ipase, to be able to recover and reuse it repeatedly ( D. S. Clark,1994;D. Cowan, 1996). Immobilization of lipase is the attachment of the enzyme onto a solid support or the confinement of the enzyme in a region of space (Jegannathan et al. , 2008). When proper strategy for the lipase immobilization technology is employed , it provides a number of important benefits including: (a)enzyme reuse, (b) easy of separation of product from enzyme and (c) the potential to run continuous processes via packed-bed reactors (Peilow and Misbah, 2001). Methods of immobilization include chemical and physical means. Among these, the physical immobilization by way of entrapment is the most widely-used method, in which enzymes are entrapped within the sol-gel matrix prepared by hydrolysis and polycondensation of precursors (Ko Woon Lee, et al. 2010). Tetramethylorthosilicate (TMOS) is a widely used precursor for sol-gel immobilization of the enzyme. However, CALB is unstable and shows low catalytic efficiency in the reaction media contains high concentration of methanol and the lipase is also inhibited by the by-product of glycerol. To overcome this, an amphiphilic matrix is developed to immobilize the lipase ((Ko Woon Lee, et al. 2010). The use of solvent in the transesterification process is also considered. Solvents are used to protect the enzyme from denaturation by alcohol by increasing alcohol solubility (Kumari et al. , 2009). The solvent can also increase the solubility of glycerol which is beneficial since the byproduct can coat the enzyme and inhibit its performance (Royon etal. , 2007 ). The use of a common solvent for the reactants and products not only reduces enzyme inhibition but also ensures a homogeneous reaction mixture, reduces the reaction mixture viscosity and stabilizes the immobilized enzyme (Ranganathan et al. , 2008;Fjerbaek et al. , 2009). This is beneficial because homogeneous reaction mixture decreases problems associated with a multiple phase reaction mixture and a reduced viscosity reduces mass transfer problems around the enzyme (Fjerbaek et al. , 2009). The use of solvents significantly increases the reaction rate in comparison to solvent free systems (Vasudevan and Briggs, 2008). Some study also showed that methanolysis conversion using Candida antarctica was increased when tert-butanol was added to the system (Royon et al. , 2007). This serve as the basis for the choice of tert-butyl to be the solvent use in the system, in order to reduce the inhibition cause of the use of a lower chain alcohol, in this case, the methanol. OBJECTIVES This study aims to produce economical source of feedstocks such as waste-cooking oil for the production of biodiesel and the use of enzyme Candida Antarctica Lipase B, to catalyze to transterification reaction. To be able to determine the yield biodiesel through Gas Chromatographic Analysis (Chrompack CP 9001, Holland). SIGNIFICANCE OF THE STUDY Oil is one of the most commonly reported types of water pollution, causing nearly a quarter of all pollution incidents. Careless disposal of oil into drainage systems, onto land or to watercourses is an offense. It can harm river birds, fish and other wildlife. Because of the way oil spreads, even a small quantity can cause a lot of harm. It is estimated that UK caterers produce between 50 ââ¬â 90 million litres of waste cooking oil each year. If this is not disposed of correctly the effects of oil pollution on the environment could be quite devastating. According to the Environmental Protection Agency (EPA), estimates that over 200 million gallons of used oil ends up in the trash, and poured into the water each year. This study aims to promote conventional and economic source for the production of biodiesel by using home waste material such as waste cooking oil. Thus, resolving high cost of biodiesel production making it commercially producible and reduce devastation of environment due to high consumption of crude oils from fossil sources. This study will be a significant endeavour in promoting the social needs and to resolve the high prices of the gasoline which is the major economical crisis face in the present society. The advantages of using lipases in biodiesel production are: (a) ability to work in very different media which include biphasic systems, monophasic system (in the presence of hydrophilic or hydrophobic (Am. J. Biochem. Biotech. , 6 (2): 54-76, 2010), (b) they are robust and versatile enzymes that can be produce in bulk because of their extracellular nature in most producing system, (c) many lipases show considerable activity to catalyze transesterification with long or branched chain alcohols, which can hardly be converted to fatty acid esters in the presence of conventional alkaline catalysts, (d) products and byproduct separation in downstream process are xtremely easier, (e) the immobilization of lipases on a carrier has facilitated the repeated use of enzymes after removal from the reaction mixture and when the lipase is in a packed bed reactor, no separation is necessary after transesterification and (f) higher thermostability and short-chain alcohol-tolerant capabilities of lipase make it very convenient for use in biodiesel production (Bacovsky et al. , 2007; Kato et al. , 2007; Robles et al. ,2009). SCOPE AND LIMITATION Like any method for enzymatic biodiesel production, the co st of the lipase to be used is one of great consideration . The limitations of using lipases in biodiesel production include (a) initial activity may be lost because of volume of the oil molecule (Marchetti et al. , 2008; Robles et al. , 2009), (b) the use of solvent does not guarantee the complete protection of enzyme from the inhibitory effect of low chain alcohol, methanol (c) Although lipase is not affected by the high content of FFAs in WCO, the high water content remains a problem (d) the lipase in the biodiesel production is limited on a specific feedstock to be used because of the regioselectivity of the enzyme lipase. CHAPTER 2 REVIEW OF RELATED LITERATURE Biodiesel has shown its ability tomeet the energy demand of the world in the transportation, agriculture, commercial and industrial sectors of the economy (Akoh et al. , 2007; Basha et al. , 2009; Shafiee and Topal, 2009; Robles et al. , 2009). The annual world consumption of diesel is approximately 934 million tons, of which Canada and the United States consume 2. 14 and 19. 06%, respectively (Marchetti et al. , 2008). As a green renewable and potentially unlimited, biodiesel has recently come out as the superlative alternative fuel which can be used in compression ignition engines with minor or no modifications (Xu and Wu, 2003; Vasudevan and Briggs, 2008; Robles et al. , 2009; Leung et al. , 2010). The concept of biofuel is not new. Rudolph Diesel was the first to use a vegetable oil (peanut oil) in a diesel engine in 1911 (Akoh et al. , 2007; Antczak et al. ,2009). The use of biofuels in place of conventional fuels would slow the rogression of global warming by reducing sulfur and carbon oxides and hydrocarbon emissions (Fjerbaek et al. , 2009). Because of economic benefits and more power output, biodiesel is often blended with diesel fuel in ratios of 2, 5 and 20% (Vasudevan and Briggs, 2008). The higher the ratio of biodiesel to diesel the lower the carbon dioxide emission (Fukuda et al. , 2001; Harding et al. , 2007). Using a mixture containing 20% biodiesel reduces carbon dioxide net emissio ns by 15. 66% (Fukuda et al. 2001) while using pure biodiesel makes the net emission of carbon dioxide zero (Vasudevan and Briggs, 2008). The simplest and most efficient route for biodiesel production in large quantities, against less ecofriendly, costly and eventual low yield methods is transesterification. One of the classic organic reactions (transesterification) is the step wise reversible reactions of a triglyceride (fat/oil) with an alcohol to form esters and glycerol. Little excess of alcohol is used to shift the equilibrium towards the formation of esters. Transesterification using an alcohol is a sequence of three reversible consecutive steps. In the first step, triglycerides are converted to diglycerides. In thesecond step, diglycerides are converted to monoglycerides. In the third step, monoglycerides are converted to glycerin molecules (Freedman et al. , 1984; Noureddini and Zhu, 1997; Marchetti et al. , 2008). Each conversion step yields one FAAE molecule, giving a total of three FAAEs per triglyceride molecule as described by the following equations (Murugesan et al. , 2009). 1. Conversion of triglycerides to diglycerides . Conversion of diglycerides to monoglycerides 3. Conversion of monoglycerides tto glycerin molecules In order for the transesterification reaction to be applicable for biodiesel production, the process must be accelerated by the use of catalyst which may be alkaline, acids or enzymes (Bacovsky et al. , 2007; Murugesan et al. ,2009; et al. , 2010). The catalyst employed directly effects the purity of the feedsto ck required, the reaction rate and the extent of post reaction processing needed (McNeff et al. , 2008). To speed up the reaction, heat is also applied. However, this process is very energy intensive and inefficient since FAAE yield below 350à °C is very low and temperatures above 400à °C degrade the ester bonds (Ranganathan et al. , 2008). Generally, the reaction mix is kept just above the boiling point of the alcohol (71-72à °C) to speed up the reaction. The variables known to affect the reaction are: temperature, alcohol to oil molar ratio, catalyst concentration and mixing intensity (Marchetti et al. ,2007). Transesterification catalysts: The transesterification process is catalyzed by alkalis, acids or enzymes. However, the use of alkali catalysts is 100% in commercial sector. The most common alkaline catalysts are sodium hydroxide (NaOH) METHODOLOGY * LIPASE CABL ( Novozyme CABL L) can be purchased from Novozyme (Denmark). All other chemicals can be purchased from Sigma- Aldrich (St. Louis, MO, USA). Grown in theà laboratory,à Candidaà appears as large, round, white or cream (albicansà is fromà Latinà meaning ââ¬Ëwhitishââ¬â¢) colonies with a yeasty odor onà agar platesà at room temperature. IMMOBILIZATION OF LIPASE Sol ââ¬â gel immobilization in an amphiphilic matrix was shown in figure below; mL of CABL (8. 2 mg/ml) is to be placed in a 50-ml Falcon tube with 1-mL of 0. 2 M phosphate buffer (pH 7). As a catalyst, 50 microliter of 1M sodium fluoride is to be added and the mixture is to be shaken with a vortex mixer. Then, TMOS (2 mM) and the following hydrophobic alkylsilanes (8 mM) is added; methyltrimethoxysilanes (MTMS), ethyltrimethoxysilane (ETMS), propyltri methoxysilanes (PTMS), and iso-butyltrimethoxysilane (iso-BTMS). Gelation is usually observed within a few minutes while a reaction vessel is gently shaken. Following complete polymerization for 12 hours in a closed Falcon tube, the gel was dried for 24 hours in an open Falcon tube. The gel is to washed with 10 mL of distilled water, 10 mL of 99. 8% iso-propanol, and 10 mL of 95% n-hexane respectively. The immobilized CALB is to be filtered using filter paper, dried at 30 for oC for 36 hours and then ground with mortar and pestle. The particles were sorted using 500 and 300 micrometer sieves and stored at 4 oC until use. ENZYME SOLUTION Immobilized P. cepacia lipase solution is prepare by adding 0. g of lipase to 1 ml of distilled water and soak in water for 30 minutes, prior to being used. This step is found experimentally essential to activate the enzymes. WASTE-COOKING OIL PREPARATION In order to ensure consistency, waste cooking oil is simulated from the commercially available palm oil by heating 1 L of palm oil on a hot plate (Stuart, U. K. ), set at its maximum heating power for two hours. The oil is then allowed to cool to room te mperature and then 5 ml of water (around 5000 ppm) is to be added. The sample is shelved for two weeks before being used. Fresh WCO samples were prepared every two weeks. Bio-Diesel Production in tert-butyl Solvent System Using C. Antarctica Lipase The experiment will be conducted in a specially designed 150 ml capacity jacketed reactor cell. The cell will be kept on a magnetic stirrer (Velp Scientifica, Italy) to facilitate the agitation of the mixture. Water from a temperature controlled water bath (Grant Instruments, UK) circulated through the jacket and will be set to maintain the temperature of the reaction media constant at 45 oC. The temperature used was that presented in the literature to be the optimum(M. M. Soumanou,et al, 2003; H. Fukuda,et al, 2001 ) and an agitation speed was chosen to provide suitable mixing without affecting the activity of the enzyme. In this part, the working volume at the beginning of each experiment was 50 ml, consisting of 5 g of WCO, different volumes of methanol, in the range of 0. 4 to 0. 8 ml (correspond to 0. 57 to 1. 14 molar equivalents of ester bonds in the triglyceride chain), and tert-butyl solution to make up the total volume. The cell is to be covered tightly throughout the progress of the experiments to prevent evaporation. After thermal equilibrium is ensured, 1 ml of enzyme solution containing 0. 4% g of C. Antarctica lipase per g oil is added to initiate the reaction. At suitable intervals, 1. 5 ml samples are withdrawn into a capped vial, immediately immersed in boiling water for at least 5 minutes to denature the enzyme and stop the reaction, and then send for analysis. The amounts of FAMEs in the samples are to be determine by using Gas Chromatograph (Chrompack CP 9001, Holland).

The assorted investing options and their after revenue enhancement outputs are shown in the undermentioned tabular array The condominium The mortgage company requires $ 10000 as the down payment for the condominium. The $ 10000 down payment will be deposited in an history which is traveling to gain involvement on top. The involvement will off-set some of the mortgage costs. The premise made here is that the mortgage investing option is the most cost effectual and therefore low-cost. Another premise is that the house is non for sale and therefore no revenue enhancement on the capital grasp. Municipal bonds Are issued by province. metropolis or local authorities. Interest received from municipal bonds are exempt from federal revenue enhancement. exempt from province revenue enhancement if brought by occupants of that province and exempt from local revenue enhancement if bought by occupant of the vicinity where the bond was issued By and large is a signifier of revenue enhancement nest eggs by people who have big revenue enhancement loads. We will write a custom essay sample on Personal Finance Essay Sample or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Outputs are much lower than corporate bonds. Corporate stock Stockss represent equity ownership in a company therefore one owns a piece of the company. Because of the high returns of stock. they are ever high hazard. The dividend received and capital additions are nonexempt. Assume no capital grasp of corporate stocks Salvaging history Offered by most commercial Bankss. There are fundamentally two types of history in the market Basic nest eggs account-the involvement offered in these type of history is normally really low but the client can be able to retreat the money if they so wish. The involvement from this history is nonexempt Money Market account-the involvement offered in this type of history is comparatively high compared to other savings histories. The lone drawback with this sort of history is that you can non freely retreat the money. The money market history involvement is non nonexempt hence presents a revenue enhancement economy High growing common stocks Common stock represents equity ownership in the company investor therefore is portion proprietor of the company. Stocks normally have high returns and therefore are high hazard besides. The capital additions and dividend. received are taxed. There are no dividends in this instance but the capital additions is 10 % Recommendation The sum of nest eggs that the Brittenââ¬â¢s have is $ 40000. We can infer from the computation of the person after revenue enhancement outputs of each of the available investings that the first option that the Brittenââ¬â¢s should put in is the Condominium. The condominium requires $ 10000 and has the highest return. From the tabular array above we can see that it has an after revenue enhancement output of 10 % . This investing option should rank as the first blackball any other factors e. g. mortgage rates. continuance and flexibleness. The 2nd investing option should theoretically be the High giving up common stocks. This is because it has the 2nd best after revenue enhancement output of 5. 76 % . However this could alter due to the hazard profile of the Brittenââ¬â¢s. If they are willing to take a high hazard since stocks are high hazard investings so they can put in this option. If they are risk averse. so the Municipal Bonds option is the manner to travel for the Brittenââ¬â¢s. This investing option has a return of 5 % after revenue enhancement. Another most obvious advantage of this sort of investing is that it is revenue enhancement free and hence revenue enhancement nest eggs. The overall investing advice is that ; Invest in the Condominium as the first option ( $ 10000 ) and so depending on the hazard profile. if hazard takers ; put the staying $ 30000 in the High Yielding Common Stocks. If hazard averse. put in the revenue enhancement free Municipal Bonds Notice here that the nest eggs history is non considered because it has much lower after revenue enhancement output.

This in kernel agencies that it does non see the current periodââ¬â¢s payments. purchases and merely credits. The monthly involvement = 16 % ? 12 = 1. 33 % Previous balance = $ 600 Therefore finance charge = 600 ten 1. 33 % = $ 8 The draw back of this method is that the publishing company can bear down the recognition card holder involvement on balances already repaid. Adjusted balance methods This method of ciphering recognition card finance charge considers all the minutess that place during the charge rhythm. This means that purchases are added. payments subtracted and credits added to the gap balance in order to get at the shutting balance in which the finance charge is calculated on ( Learn Money: 2008 ) .

But this is the instance merely because Nancy made merely one payment while bear downing more. Otherwise the best method for the recognition card holder is the adjusted balance method in that it considers all payment. credits and purchases. Therefore. if Nancy had made more payments. her finance charge would be much lower under adjusted balance method. This method works best if the recognition card holds repays more. The ideal method if the recognition card holders wish to increase the outstanding balance is the old balance method. this is because the current finance charge is calculated on the old balance which would be lower than current balance.
