A Mexican firm is thinking about borrowing in USD at $3$ percent per year.The spot exchange rate for the Mexican peso $($MXN$)$ is $20$ MXN $/$USD$.$The one$-$year forward rate is $21$ MXN$/$USD$.$Suppose you fully hedge the exchange rate risk of the loan.What does the $3$ percent interest rate in USD correspond to in MXN$?$Note: write your answer as a percentage, and with two decimal places. For example, if the answer is $4\mathrm{.}876\%,$ you should write $4\mathrm{.}88.$
