Joey has a credit card that uses the previous balance method. the opening balance of one of his 30-day billing cycles was $0, but this was his balance for only the first 15 days of the billing cycle. he then made a purchase that increased his balance to $7200, and his balance stayed this amount for the remainder of the billing cycle. if his credit card's apr is 13%, how much was joey charged in interest for the billing cycle?
