The mcgee corporation finds it necessary to determine its marginal cost of capital. Mcgee's current capital structure set calls for 50% debt, 20% preferred stock, and 30% common equity. Initially, common equity would be in the form of retained earnings(Ke) and then new common stock(Kn). The cost of the various sources of financing are as follows: debt, 6.2%, preferred stock, 7.0%, retained earnings, 13%, and new common stock, 14.4%

c. what will the marginal cost of capital be immediately after that point?(equity will remain at 30% of the capital structure, but will all be in the form of new common stock, Kn)

d. the 6.2% cost of debt referred to above applies only to the first $28 million of debt. After that, the cost of debt will be 9.2%. At what size capital structure will there be a change in the cost of debt?
