NO.PZ2018062016000017 问题如下 Bella set a new account for her worli-traveling plan. She plans to funabout $100,000 in five years anposit cash in this account every month. Assume the stateannurate is 3% ancompounmonthly, the amount thBella hto put into the account eamonth is: A.$1,547 B.$1,570 C.$1,670 A is correct. Input the following ta in the calculator ENmo: N=5*12=60, I/Y=3/12, FV=100,000, PV=0, then PMT=-1,547. Therefore, the monthly posit for Bella is $1547. 我有个问题一直没搞明白。如果我算EAR的话就是(1+0.03/12)的12x5次方.这个公式是算的什么?我总是不知道一道题什么时候算E什么时候又可以直接按计算器

如果EAR算出3.0416%,代入N=5,I/Y=3 .0416,PV=0,FV=100000,算出年PMT=18819.8,再除以12就是1568,请问哪里不对?
