Consider a firm with $61.5 in outstanding debt and $69.29 in equity. If the required return on debt is 8.269%, the required return on equity is 11.422%, and the firm's tax rate is 22%, find the firm's weighted-average cost of capital to four decimal places. Assume no preferred stock is issued. For example, 0.0456 for 4.56%, not 0.04 or 4.56.
