BASED ON THIS

1. Shirley, a recent college graduate, excitedly described to her older sister the $1,500 sofa, chair, and tables she found today. However, when asked, she could not tell her sister which interest calculation method was to be used on her credit-based purchase. Calculate the monthly payments and total cost for a bank loan assuming a 1-year repayment period and 14 percent interest. Now, assume the store uses the add-on method of interest calculation. Calculate the monthly payment and total cost with a 1-year repayment period and 12 percent interest. Explain why the bank payment and total cost are lower even though the stated interest rate is higher.
2. Anser this---- Using the information on the two loans described in Problem 2, how much interest will Shirley save or be rebated if she can repay the loans after 6 months?Which results in a lower total interest charge, borrowing $1,000 to be repaid 12 months later as a single-payment loan or borrowing $1,000 to be repaid as a 12-month installment loan? Assume a simple interest method of calculation at 12 percent interest. Defend your answer.
