Consider a firm with $60.99 in outstanding debt and $128.45 in equity. If the required return on debt is 8.467%, the required return on equity is 12.782%, and the firm's tax rate is 26%, 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%, nor 0.04 or 4.56
