Larry loves music. He bought $285 worth of MP3 files
on his credit card, and now he
cannot afford to pay off his debt.
If the credit-card company
charges him 18% annual interest
compounded monthly, how does
Larry's debt grow as time
passes? How much would he
owe at the end of the year if he
had a "no payments for 12
months" feature for his credit
card?
