Irene has a credit card that uses the previous balance method. The opening balance of one of her 30-day billing cycles was $2510, but that was her balance for only the first 5 days of the billing cycle, because she then paid off her entire balance and didn't make any new purchases. If her credit card's APR is 11%, which expression could be used to calculate the amount Irene was charged in interest for the billing cycle?

A. ((0.11/365)*30)($2510
B.((0.11/365*30)($0)
c.((0.11/365)*30)((5*$2510+25*0)/30)
D.((0.11/365*30)((5*0+25*2510)/30)
