Please show steps and calculations as I would like to see if I am doing this right. Thanks!

Roxie Epoxy's balance sheet shows a total of $50 million long-term debt with a coupon rate of 8.00% and a yield to maturity of 7.00%. This debt currently has a market value of $55 million. The balance sheet also shows that that the company has 20 million shares of common stock, and the book value of the common equity (common stock plus retained earnings) is $65 million. The current stock price is $8.25 per share; stockholders' required return, rs, is 10.00%; and the firm's tax rate is 40%. Based on market value weights, and assuming the firm is currently at its target capital structure, what WACC should Roxie use to evaluate capital budgeting projects?

Answer options: 1) 7.26% 2) 7.56% 3) 7.88% 4) 8.21% 5) 8.55%
