Answer: 12.2%
Explanation:
Given the variables available, the required rate of return can be computed using the Capital Asset Pricing Model with the formula;
Required Return = Risk-free rate + beta ( Market risk premium)
Required return = 4.25% + 1.4 * 5.5%
Required return = 4.25% + 7.7%
Required return = 12.2%
Note; The actual question says the Risk-free rate is 4.25%.
