One of your customers is delinquent on his accounts payable balance. You’ve mutually agreed to a repayment schedule of $570 per month. You will charge .97 percent per month interest on the overdue balance. If the current balance is $14,790, how long will it take for the account to be paid off?

Note: Do not round intermediate calculations and round your answer to 2 decimal places, e.g., 32.16.
