问题如下:
Mary has a separate account for her annual savings which has a stated annual rate of 3% and compounding quarterly. At the end of each year, she transfers unequal cash flows into this account. Year 1: $500, Year 2: $800, Year 3: $0, Year 4: $300, Year 5: $500. How much will Mary save for her account at the end of year 5?
选项:
A.$2246.81
B.$2247.65
C.$2281.00
解释:
B is correct.
请老师看看我这个计算过程是哪里有问题:
先算出EAR=3.034%。
然后分别按每年计算之后加总,比如第一年就是:500*(1+3.034%)5次方=580.59,以此类推,算出来之后再5年加总。请问这个错在哪里?谢谢!
