Final answer:
The appropriate required return of MFI using the CAPM is 10.8%.
Step-by-step explanation:
The appropriate required return of MFI using the CAPM can be calculated using the formula:
Required Return = Risk-Free Rate + Beta * (Market Return - Risk-Free Rate)
Given that the beta of MFI Inc. is 0.8, the expected market return is 12% and the risk-free rate is 6%, we can plug in these values into the formula:
Required Return = 6% + 0.8 * (12% - 6%)
Calculating the value:
Required Return = 6% + 0.8 * 6% = 6% + 4.8% = 10.8%
Therefore, the appropriate required return of MFI using the CAPM is 10.8%.
