Answer:
Risk Free Rate of Return = 2.25%
Step-by-step explanation:
The real risk-free rate is the difference between yield of the Treasury Bill and Inflation rate (matching investment duration).
Risk Free Rate of Return = T-Bill Yield - Inflation Rate
= 5.5% - 3.25%
= 2.25%
The risk-free rate is the minimum rate of return an investor would expect from any investment because he will not accept any sort of additional risk unless the potential rate of return is greater than the aforementioned risk-free rate.
