Answer:
The nominal rate of return is 9%.
Step-by-step explanation:
The reason is that the International Fisher Effect says that the real return on a same investment in different countries is same. It also says that the nominal rate of return difference in two countries is due the inflation rate difference. The nominal rate of return is summation of the two interest rates which is inflation rate and real interest rate.
So
Nominal interest rate = 5% Inflation Rate + 4% Real Return = 9% Nominal rate
