问题如下：
If an investor intends to earn $100 in three years assuming the interest rate is 8.87% constantly, how much should he invest now ?
选项：
A.$77.75.
B.$77.50.
C.$100.
解释：
B is correct.
N = 3; I/Y = 8.87; PMT = 0;FV=100, CPT PV = -$77.50
题干说wants to earn $100，难道不是FV=100+PV吗？应该用公式 PV（1+8.87%）³ = 100 + PV吗？
