thank you so much

Calculation of individual costs and WACC Dillon Labs has asked its financial manager to measure the cost of each specific type of capital as well as the weighted average cost of capital. The weighted average cost is to be measured by using the following weights: 35% long-term debt, 15% preferred stock, and 50% common stock equity (retained earnings, new common stock, or both). The firm's tax rate is 29%. Debt The firm can sell for $1015 a 11-year, \$1,000-par-value bond paying annual interest at a 7.00% coupon rate. A flotation cost of 3% of the par value is required. Preferred stock 9.00% (annual dividend) preferred stock having a par value of $100 can be sold for $88. An additional fee of $5 per share must be paid to the underwriters. Common stock The firm's common stock is currently selling for $60 per share. The stock has paid a dividend that has gradually increased for many years, rising from $2.75 ten years ago to the $5.16 dividend payment, D0, that the company just recently made. If the company wants to issue new new common stock, lt will sell them $3,50 below the current market price to attract investors, and the company will pay $3.00 per share in flotation costs. a. Calculate the after-tax cost of debt. b. Calculate the cost of preferred stock. c. Calculate the cost of common stock (both retained earnings and new common stock). d. Calculate the WACC for Dillon Labs. Before-tax cost of debt and after-tax cost of debt David Abbot is buying a new house, and he is taking out a 30 -year mortgage. David will borrow $195,000 from a bank, and to repay the loan he will make 360 monthly payments (principal and interest) of $1,215.90 per month over the next 30 years. David can deduct interest payments on his mortgage from his taxable income, and based on his income, David is in the 32% tax bracket. a. What is the before-tax interest rate (per year) on David's loan? b. What is the after-tax interest rate that David is paying
