Answer:
real interest rate = -3.08%
Explanation:
real interest rate = nominal rate - inflation rate
real interest rate = 10.41% - 13.49% = -3.08%
since the real interest rate is negative, the investor actually lost money in real dollars. This means that the amount of goods that the investor could purchase before making the investment is higher than the amount of goods he/she will be able to buy after the investment.
