问题如下：
The value in six years of $75,000 invested today at a stated annual interest rate of 7% compounded quarterly is closest to:
选项：
A.
$112,555.
B.
$113,330.
C.
$113,733.
解释：
C is correct
as shown in the following (where FV is future value and PV is present value):
FV = PV(1 + rs /m)mN FV6 = $75,000(1 +0.07/4)(4×6) FV6 = $113,733.21.
老师请问，求出EAR是0.516443，这个公示求FV哪里不对? 75000*(1+0.516443)^6 结果不对

N=24，PV=-75000，I/Y=7/4=1.75，PMT=75000*7%/4，求FV。请问老师为什么正确答案中的PMT为0，谢谢老师。
