问题如下：
An analyst gathered the following Information about the capital structure and before-tax component costs for a company. The company’s marginal tax rate is 40%.
The company’s weighted average cost of capital (WACC) is closest to:
选项：
A.8.55%.
9.95%.
10.00%.
解释：
As the target capital weights are not given, you can use market value weights to compute the WACC. The market value weights for debt, preferred stock and equity are 0.2667, 0.0667, and 0.6667 respectively.
WACC=Wd * rd (1 -t) + Wp * rp + We * re
= 0.2667 * 8%(1 - 0.4) + 0.0667 * 10% + 0.6667 * 12% = 9.95%
这种题目一定要保留小数点后面几位数代入算吗？
我只保留了后一位，其他都是一样的，算出来差别还挺大的
