Notes Over 5.1 Modeling Exponential Growth 9. A customer purchases a television set for $800 using a credit card. The interest is charged on any unpaid balance at a rate of 18% per year compounded monthly. If the customer makes no payment for one year, how much is owed at the end of the year? The customer would owe $ compounded monthly $800 18% one year
