Assume that your firm's marginal tax rate is 35% and that your firm has the following capital structure:

Bonds:

coupon rate = 6%

yield-to-maturity = 6.5%

Market value of bonds = $25 million

Book value of bonds = $30 million

Common stock:

Book value of common shares = $25 million

Market value of common shares = $50 million

Required rate of return (r) = 10.5%

What is your firms Weighted Average Cost of Capital (report as a raw number, i.e. if it is 10.43%, plug in 10.43)?
