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:
