问题如下:
Tom has twin daughters Lucy and Lily at 12 years old. Six years later, both will study in a famous university in California for four years with a tuition fee of $6,000 paid at the beginning of each year per person. Assume the annual discount rate is 5%, today Tom should prepare:
选项:
A.
$16,670
B.
$33,340
C.
$31,753
解释:
B is correct. Six years later, Tom will pay tuition fee of $12,000 each year and last for 4 years, as he has two daughters. The payment is paid in the front, therefore set the calculator at BGN mode and input: N=4, I/Y=5%, PMT=12,000, FV=0, then PV=44678.98. The value of tuition fund at year 6 is $44,678.98, so the present value is $44,678.98/(1+5%)6=$33,340.
6年后为什么不是19那个点开始第一笔现金流到22节点呢?这种题目一直分不清这中间的节点和具体N是怎么算出来的,一次都没做对过,有没有容易理解的方法
