APR stands for Annual Percentage Rate and in this problem, we are given APR is equal to 9.7%

Per month rate = 9.7% / 12 months = 0.808%

Total credit interest for 12 months = 958.62 * 0.097 = $92.97

In one month = $92.97/12 = $7.7475

If you pay at the end of the first month:

Payment = 105.00

The amount goes to principal:

Amount = $105 - $ 7.7475

Amount = $142.25
