Question: 1. Calculating the effective annual rate) You've just received an offer from a bank for a credit card with a quoted rate, or APR, of 18 percent compounded monthly. What's the EAR, or effective annual rate, on the credit card?
2. (Calculating an APR and EAR) You're in need of some money fast, and rather than ask your folks for help, you've decided to look into a payday loan. At a payday loan shop right near your school you see that you can borrow $100 and repay $115 in 10 days. What are the APR and the EAR on this payday loan?
