The balance at the beginning of the second month on the credit card, based on a 12.75% APR, is <u>$28,02.85.</u>

The APR or annual percentage rate is the cost of finance charged to the borrower of a loan or a credit cardholder.

When the APR is divided by 12 months, it results in MPR, which can be used to determine the interest.

<h3>Data and Calculations:</h3>

Credit card balance at the beginning of the first month = $2,744.69

APR = 12.75%

Monthly APR = 1.0625% (12.75/12)

Late Fee = $29

Ending balance at the beginning of second month = <u>$28,02.85</u> ($2,744.69 x 1.010625% + $29)

Thus, the balance at the beginning of the second month on the credit card, based on a 12.75% APR, is <u>$28,02.85.</u>
