Empire Electric Company $($EEC$)$ uses only debt and common equity. It can borrow unlimited amounts at an interest rate of $r_d=10\%$ as long as it finances at its target capital structure, which calls for $40\%$ debt and $60\%$ common equity. Its last dividend $(D_0)$ was $$2\mathrm{.}85,$ its expected constant growth rate is $3\%,$ and its common stock sells for $$24.$ EEC's tax rate is $25\%.$ Two projects are available: Project A has a rate of return of $13\%,$ and Project B$\text{'}$s return is $12\%.$ These two projects are equally risky and about as risky as the firm's existing assets.
