Hank purchased a car for $$21,000$ two years ago using a $3-$year loan with an interest rate of $7\mathrm{.}2$ percent. He has decided that he would sell the car now, if he could get a price that would pay off the balance of his loan.

What$$s the minimum price Hank would need to receive for his car? Calculate his monthly payments, then use those payments and the remaining time left to compute the present value $($called balance$)$ of the remaining loan.

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