Answer:
a. 10.04%
b. $82.78
Step-by-step explanation:
In this question, we apply the Capital Asset Pricing Model (CAPM) formula which is shown below 
a. Expected rate of return or market capitalization = Risk-free rate of return + Beta × (Market rate of return - Risk-free rate of return) 
= 5% + 0.72 × (12% - 5%) 
= 5% + 0.72 × 7% 
= 5% + 5.04% 
= 10.04%
The Market rate of return - Risk-free rate of return) is also known as the market risk premium and the same is applied. 
b. Now the intrinsic value would be
= Expected dividend ÷ (Required rate of return - growth rate) 
= $5 ÷ (10.04% - 4%) 
= $5 ÷ 6.04% 
= $82.78
