Julia Foster does not believe that the international Fisher effect $($IFE$)$ holds. Current one$-$year interest rates in Mexico are $11\mathrm{.}60$ percent, while one$-$year interest rates in the U$.$S$.$ are $5\mathrm{.}10$ percent. Julia Foster converts $$100,000$ to the Mexican pesos and invests them in Mexico for one year. One year later, she converts Mexican pesos back to dollars. The current spot rate of the Mexican peso is $$0\mathrm{.}0600.$

If the spot rate of the Mexican peso in one year is $$0\mathrm{.}0550,$ what is Julia Foster's percentage return from her strategy?
