一笔钱投资一年,单利2%, 另一笔10,000复利,以半年算,一年的复利是4%,结果两个利润一样。问第一笔钱是多少?
我觉得式子应该这么列:X * 2% = 10,000 (1+ 4%/2)^2 - 10,000
以半年计的复利是不是应该像右边这样算利润的呢?
还是像给的参考答案那样,只是10,000(1+ 4%/2)- 10,000 没有平方呢??

恩,我算出来也是20200的
should have a square
A=P(1+r/n)^nt
P = principal amount (the initial amount you borrow or deposit)
r = annual rate of interest (as a decimal)
t = number of years the amount is deposited or borrowed for.
A = amount of money accumulated after n years, including interest.
n = number of times the interest is compounded per year
Compounded interest formula
Thanks Hang 13
I fixed my formula too!
