Harvey has a credit card that uses the previous balance method. The opening
balance of one of his 30-day billing cycles was $2790, but that was his
balance for only the first 6 days of the billing cycle, because he then paid off
his entire balance and didn't make any new purchases. If his credit card's APR
is 21%, which of these expressions could be used to calculate the amount
Harvey was charged in interest for the billing cycle?
