Suppose that 16 years ago, you borrowed a certain amount of money. The loan had an annual interest rate of 6.5% with continuous compounding, and today you repaid a total of $85,751.

How much interest did you pay on this loan, as a percentage of how much you borrowed? For example, if you borrowed $1000 and you paid $175 in interest, the answer would be 17.5 (percent).

Round your answer to the nearest percent.
