Carl won a prize of $21,391$ dollars that will be paid out $7$ years from now. If the

interest rate is $6\mathrm{.}65\%$ per year, what is the value of Carl's future prize money today?

In other words, if the prize were paid out now $($instead of waiting $7$ years$),$ how

much would Carl be paid today? $($note: round your answer to two decimal

places; do not include spaces or dollar signs.$)$
