问题如下：
John receive a gift from his grandpa about $1.2 million. He plans to buy a house in five years later, which price is expected to be $250,000 at that time. How much should John deposit now if the stated annual rate is 3% and compounded monthly?
选项：
A.
$215,652
B.
$215,217
C.
$242,620
解释：
B is correct. Present value * (1+3%/12)12*5=$250,000, therefore, John should deposit $215,217 currently.
老师您好，为什么可以判断n是5而不是4啊？five years later 是说第五年年初还是年底呢
