Final answer:
The real rate of return for an investment with a nominal return of 20.4% and an inflation rate of 2.5% is 17.9%, rounded to two decimals.
Step-by-step explanation:
To calculate the real rate of return, we need to adjust the nominal return by the inflation rate. The formula for the real rate of return is given by:
Real Rate of Return = Nominal Rate of Return - Inflation Rate
You made an investment with a nominal return of 20.4%. With an inflation rate of 2.5%, we can calculate the real rate of return as follows:
Real Rate of Return = 20.4% - 2.5% = 17.9%
Therefore, the real rate of return for this investment would be 17.9% when rounded to two decimals, which you would enter as 17.90 without the percentage sign.
