You lose your job and decide to charge some of your grocery bills on your credit card. An average monthly grocery bill for a family of 4 is $600. In the year you were out of work, you managed to charge $3,600 in groceries on your credit card which has an annual interest rate of 16.99%. Assume that you only pay the minimum payment of 3% or $25 (whichever is greater), and also that you make no other purchases with your credit card. How many months will it take you to pay off your balance? How much interest will you pay?
