Leroy's credit card has an APR of 21%, calculated on the previous monthly
balance, and a minimum payment of 2%, starting the month after the first
purchase. His credit card record for the last 7 months is shown in the table
below.
How much of the initial purchase has Leroy paid off over the 7 months?
A. $310.06
B. $271.30
C. $44.93
D. $38.76

Either A or C this is what I think cross off B and D you'll have to do the math for the two percent and the twenty-one I'm still foggy of this.
