Using the uncovered interest parity, if the return on United States dollar deposits (i_$) is 0.5%, the expected dollar-peso exchange rate (E^e_$/MP) is $0.04 per peso, and dollar-peso spot rate(E_$/MP) is $0.05, what is the return on peso deposits (i_MP)?

(Hint: When you're doing the calculations, convert the peso interest rate into a decimal [i.e., 0.005]. Once you have your answer, convert it back to a percentage.)
