First we want to calculate total payments of each payment in order to find the interest. After that calculate the difference to get the answer
Total payments of 625.77
625.77×12months×3 years
=22,527.72
Interest paid
22,527.72−14,350
=8,177.72
Total payments of 431.21
431.21×12months×3 years
=15,523.56
Interest paid
15,523.56−14,350
=1,173.56
So how much more in interest did Cheri end up paying for her loan because of her bankruptcy
8,177.72−1,173.56
=7,004.16...answer
Hope it helps!
