问题如下：
Company M, a manufacturer of automobile, is in the 25% tax bracket. The company is currently 37.5% debt-financed and 62.5% equity-financed, with the market value of debt and EBIT of $1 million and $0.5 million, respectively. What`s the WACC of Company M according to the MM`s proposition with tax?
选项： 11.25%
14.04%
C.18.73%
解释：
B is correct.
考点：Capital Structure Theory: with tax
解析：根据公式
VD = $1 million, D/E = 0.6, 求得VE = $1.67 million
代入VL = 2.67 = ，求得WACC = 14.04%
vu和vl的计算公式可以列一下吗？没有看懂

同学你好, 关于 Vu 和 VL 的计算公式, 李老师在基础班视频中专门总结过.
其中, VL 可以从两个角度出发理解
- 无杠杆的价值, 加上有杠杆的税盾
- 资产负债表右边等于左边
请参考

这道题求的是 WACC, 无法直接使用定义公式计算, 因为 re 和 rd 均未知, 可以借助 VL 的第二个角度的公式去推导.
我把公式推导过程附上了, 请参考.
关于 MM 理论的计算题, 套路不多, 建议再多做一些题目熟悉一下. 李老师上课提到的例题, 也可以再回顾一下. 加油!
