Final answer:
The required rate of return using the CAPM can be calculated using the given values of risk-free rate, beta, and market rate of return.
Step-by-step explanation:
The required rate of return using the CAPM (Capital Asset Pricing Model) can be calculated using the formula:
R = Rf + β * (Rm - Rf)
Where:
- R is the required rate of return
- Rf is the risk-free rate
- β is the beta of the asset
- Rm is the market rate of return
Plugging in the given values:
R = 5% + 2 * (10% - 5%) = 15%
Therefore, the required rate of return using the CAPM is 15% (option c).
