Chapter 11-30 points question regarding Coleman technologies, can you please show all of the steps to get the WACC for using the retained earnings as the equity component? I need to see HOW you got this answer. Please

This one:

I was recently hired as an assistant to the financial VP of Coleman Technologies and my first task is to estimate Coleman's cost of capital. The VP has provided me with the information below, which he believes is relevant to my task.

(1) The firm's marginal tax rate is 40%.

(2) The current price of Coleman's 15-year, 12% coupon (semiannual interest payments) bonds is $1,153.72. Coleman does not use short-term interest-bearing debt on a permanent basis. New bonds would be privately placed with no flotation costs.

(3) The current price of the firm's 9%, $100 par value preferred stock is $105. Coleman would incur flotation costs of 4.8% to issue new preferred stock.

(4) Coleman's common stock is currently selling at $50 per share. Its last dividend (D₀) was $4.19, and dividends are expected to grow at a constant rate of 5% in the foreseeable future. Coleman's beta is 1.2, the yield on Treasury bonds is 7%, and the market risk premium is estimated to be 6%. For the bond-yield-plus-risk-premium approach, the firm uses a 4%-point risk premium.

(5) Up to $300,000 of new common stock can be sold at a flotation cost of 15%. Above $300,000, the flotation cost would rise to 25%.

(6) Coleman's target capital structure is 30% debt, 10% preferred stock, and 60% common equity.

(7) The firm is forecasting it will retain earnings equal to $300,000 in the coming year.

After reviewing this information, the VP has asked me to do the following two things.

I am choosing option B to answer the following questions.

Option #B1 - What is Coleman's overall, or weighted average, cost of capital (WACC) when retained earnings are used as the equity component? You must show your work as well as explain why.
