I am looking for help on the following question. I need to ultimately calculate the WACC with the following assumptions.

1. Calculate the WACC given the following assumptions:
   1. Company tax rate is 40%.
   2. Company has an outstanding bond issue with a 6-7/8 coupon, market price of 102-5/8 (percent of 100% par, in 32nds), semiannual coupon payments, and 12 years to maturity.
   3. Company has an outstanding preferred stock issue paying an 8% dividend, $100 par, and a market price of $98.35. Flotation (issuance) costs on a new issue are 8%.
   4. Common equity financing is through retained earnings. The company has a beta of 1.22. The market risk premium is 6% and the risk-free rate is 4%. The company's capital structure is 40% debt, 10% preferred, and 50% common equity.
