问题如下：
A firm is planning to construct a $10,000 production line. Assume a required rate of return of 8%, given the cash flows for this plan:
The internal rate of return (IRR) for the project is closest to:
选项：
A.8.00%.
B.15.00%.
C.10.65%.
解释：
C is correct.
CF0 = -10,000, CF1 = 5,000, CF2 = 4,000, CF3 = 3,000. Then CPT IRR = 10.65%.
老师这道题里的Required rate of return为什么没用啊？
