This week we will be studying the mathematics of finance. Most people take out a loan for making big purchases like a home or a car. People who have a balance on their credit card are borrowing money. Some investigation is often required to find the Best Deal. Please post your solution to one of the following problems: a) Calculate the amount of simple interest earned : $3,500 at 7% for 3 years b) Find the future value : $475 at 3.25% compounded daily for 5 years c) Karen and Wayne need to buy a refrigerator because theirs just broke. Unfortunately, their savings account is depleted, and they will need to borrow money in order to buy a new one. Sears offers them an installment loan at 16 %( add-on rate). If the refrigerator at Sears costs $1,540 plus 5% sales tax, and Karen and Wayne plan to pay for the refrigerator for 3 years, what is the monthly payment?
