Answer:
a. 16.50%
Explanation:
Find the beta as of last year using CAPM;
CAPM ; r = risk free + beta(Market risk premium)
0.125 = 0.03 + beta(0.0475)
Subtract 0.03 from both sides;
0.125-0.03 = 0.0475beta
0.095 = 0.0475beta
Divide both sides by 0.0475;
0.095/0.0475 = beta
beta = 2
Next, use CAPM again to find the new required return with a market risk premium is 4.75%+ 2% = 6.75%
r = 0.03 + 2(0.0675)
r = 0.03 + 0.135
r = 0.165 or 16.5%
Therefore, the new required return is 16.5%
