Compute the WACC for a company in the 21% tax bracket if it has a $10 million bond issue with 15 years to maturity a 5% annual coupon (paying semi-annually) and a market price of $945; $3 million of $50 par value preferred stock with a price of 90% and an annual dividend of $2.00; and 3 million shares of common stock at a current price of $10 and a beta of 1.4 when the risk free rate of return is 3% and the market rate of return is 11%

Give me a step by step example on how to solve this please. I am very lost.
