Consider a company which has $\beta_{\text {equily }}=1.5$ and $\beta_{\text {act }}=0.4$. Suppose that the risk-free rate of interest is $6 \%$, the expected return on the market $E\left(r_M\right)=15 \%$, and that the corporate $\operatorname{tax}$ rate is $40 \%$. If the company has $40 \%$ equity and $60 \%$ debt in its capital structure, calculate its weighted average cost of capital using both the classic CAPM and the taxadjusted CAPM.
