I need help finding how to solve this. I found that the answer was 5%, but I'm not sure how to solve it.

Assume that the U.S. one-year interest rate is 5% and the one-year interest rate on euros is 8%. You have $100,000 to invest and you believe that the international Fisher effect (IFE) holds. The euro's spot exchange rate is $1.40. What will be the yield on your investment if you invest in euros?
