If you have a choice to earn simple interest on $10,000 for three years at 8.5% or annually compound interest at 8% for three years which one will pay more and by how much?
答
这句话意思是一个计算题.
如果你有一个选择,能够获得简单的利息,10000美元的三年每年在8.5%或者三年复利8%,你将选择那一种能够多获得利息?能够获得多少利息?
这是一个计算题.其实就是单利和复利的问题.
单利每年8.5% ,则每年获得利息为10000X0.085=850元,三年将获得利息850X3=2550元
复利每年8%,则三年获得利息将是10000X（1+8%）的3次方 -10000= 2597元
看来还是复利比较划算啊,三年多了47元
