Consider a firm with $$35\mathrm{.}85$ in outstanding debt and $$98\mathrm{.}53$ in equity. If the required return on debt is $4\mathrm{.}623\%,$ the required return on equity is $12\mathrm{.}039\%,$ and the firm's tax rate is $25\%,$ find the firm's weighted$-$average cost of capital to four decimal places. Assume no preferred stock is issued. For example, $0\mathrm{.}0456$ for $4\mathrm{.}56\%,$ not $0\mathrm{.}04$ or $4\mathrm{.}56.$ using excel
