Suppose the real risk-free rate is 3.05% and the future rate of inflation is expected to be constant at 2.10%. What rate of return would you expect on a 1-year Treasury security, assuming the pure expectations theory is valid? Include cross-product terms, i.e., if averaging is required, use the geometric average. (Round your final answer to 2 decimal places.) a. 5.21% b. 2.16% c. 3.11% d. 5.15% e. 3.05%
