One of your customers is delinquent on his accounts payable balance. You've mutually

agreed to a repayment schedule of $$500$ per month. You will charge $1\mathrm{.}7$ percent per

month interest on the overdue balance.

If the current balance is $$16,000,$ how long will it take for the account to be paid off? $($Do

not round intermediate calculations and round your final answer to $2$ decimal places.

$($e$.$g$.,32\mathrm{.}16))$
