Consider a firm with $22.45 in outstanding debt and $142.4 in equity. If the required return on debt is 5.554%, the required return on equity is 14.564%, and the firm's tax rate is 17%, 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.
