问题如下:
A saver deposits the following amounts in an account paying a stated annual rate of 4%, compounded semiannually:
At the end of Year 4, the value of the account is closest to:
选项:
A.$30,432
B.$30,447
C.$31,677
解释:
B is correct.
To solve for the future value of unequal cash flows, compute the future value of each payment as of Year 4 at the semiannual rate of 2%, and then sum the individual future values, as follows:
根据上表所示,首先计算每笔存款的FV,但是需使用semiannual rate 2%,然后将FV相加求和。
题干里给的是每年年末的deposit。第一年4000,第二年8000,第二年8000里面不会有4000已经compound到第四年年末了吗?再计算8000的compound为什么没有重复计算的问题?
