The total cost for the meal for his group of friends including the tip is $135.47. His credit card has an interest rate of 24.99%. If he makes payments of $25 per month, how long would it take him to pay for that spontaneous purchase? How much would Jim end up spending on this purchase? How much interest did he pay?
