Consider a firm with $$70\mathrm{.}60$ in outstanding debt and $$165\mathrm{.}30$ in equity. If the required return on debt is $9\mathrm{.}485\%,$ the required return on equity is $8\mathrm{.}733\%,$ and the firm's tax rate is $27\%,$ 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 $4\mathrm{.}56.$
