Answer:
11.62%
Step-by-step explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below
Expected rate of return = Risk-free rate of return of treasury bond + Beta × (Market rate of return - Risk-free rate of return)
= 5.25% + 0.88 × (12.50% - 5.25%)
= 5.25% + 0.88 × 7.25%
= 5.25% + 6.38%
= 11.63% approx
