Carmel Ridge Corporation is trying to determine its optimal capital structure. The company's capital structure consists of debt and common stock. In order to estimate the cost of debt, the company has produced the table below. The applicable tax rate is 40%. The company uses the CAPM to estimate its cost of common equity. The risk-free rate is 4 percent and the market risk premium is 5 percent, while the beta without any debt (its unlevered beta") is 0.50. What is the Cost of Equity using CAPM at "50% Debt, 50% Equity" capital structure? [NOTE: Round off your answer to the nearest whole number. No need to put percentage sign] * Debt-to-total Equity-to-total Before-tax assets ratio assets ratio cost of (wa) (w) debt 0.10 0.90 0.20 0.80 5.2. 0.30 0.70 6.0 0.40 0.60 6.8. 0.50 0.50 7.6
