Bradley currently has a Visa card from his bank with the following terms: 21 percent on purchases, 25 percent on cash advances with a 3 percent cash-advance fee on the amount, and a default or penalty rate of 33 percent? His current statement shows a balance of $9,000. Lately, he has been having a hard time paying more than the minimum payment of 3 percent of his balance:

a) What is the current APY (ANNUAL PERCENTAGE YIELD) on this credit card?

b) What is the APY on Bradley's default, or penalty, rate?

c) If Bradley buys a new game console for $560 this month and sends in a credit card payment of $950 when he gets his statement, how much interest will he pay on the game console for the month?
