If the firm wants to finance total assets of $200 million, the marginal cost of capital will be?
选项：
A.6.28%.
B.5.28%.
C.5.68%.
解释：
C is correct.
The firm will need to raise $100 million in additional capital. Recall that the target capital structure of 60% equity, 40% debt, so the firm will need to raise $60 million in new equity and $40 in new debt. According to the capital schedule, the marginal cost of capital at that point will be (0.4 x 3.7%) + (0.6 x 7.0%) = 5.68%.
老师，表格里面的融资成本是不包括原来的100million资金的吗？
