Zoe filed for bankruptcy several years ago and now wants to take out a loan for $15,200. Since Zoe has a past bankruptcy, she will end up paying a higher interest rate. The loan term is four years, and her payments are $819.20 per month. With a better credit rating, her payments could have been $440.82 per month. How much more in interest will Zoe end up paying for her loan because of her bankruptcy?
