You have been pricing an MP3 player in several stores. Three stores have the identical price of $400. Each store charges 18 percent APR, has a 30-day grace period, and sends out bills on the first of the month. On further investigation, you find that store A calculates the finance charge by using the average daily balance method, store B uses the adjusted balance method, and store C uses the previous balance method. Assume you purchased the MP3 player on May 5 and made a $100 payment on June 15. What will the finance charge for June be if you made your purchase from store A? From store B? From store C?

Six-Month Loan Interest cost Total amount due After visiting several automobile dealerships, Richard selects the used car he wants. He likes its $16.700 price, but financing through the dealer is no bargain. He has $2.500 cash for a down payment, so he needs an $14,200 loan. In shopping at several banks for an installment loan, he learns that interest on most automobile loans is quoted at add-on rates. That is, during the life of the loan, interest is paid on the full amount borrowed even though a portion of the principal has been paid back. Richard borrows $14,200 for a period of four years at an add-on interest rate of 8 percent. (a) What is the total interest on Richard's loan? (Do not round intermediate calculations.
