1. Karou is considering different options for financing the $12,000 balance on her planned new car purchase. The cheapest advertised rate among the local banks is 7 percent for a 48-month car loan. The current rate on her revolving home equity line is 8 percent. Karou is in the 25 percent federal tax bracket and 5 percent state tax bracket and she uses itemized deduction for her tax return. Which loan offers lower monthly payment? Which loan has the lower after-tax cost? Which loan should she choose?

2. Shirley, a recent college graduate, excitedly described to her old sister the $4,500 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 payment and total cost for a bank loan assuming a 1-year repayment period and 12 percent simple 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 10 percent interest. Explain why the bank payment and total cost are lower even though the stated interest rate is higher.
