问题如下：
An investor purchased an annuity many years ago. The first payment of the annuity is to be received today. Assume the payment of the annuity is $5,000 constanly , the period the payment is 20 years. and the discount rate is 12%, calculate the today' value of the annuity:
选项：
A. $37,347.
B. $403,493.
C. $41,829.
解释：
C is correct.
Under the BGN mode.
N = 20; PMT = -5,000; I/Y =12; FV = 0; CPT PV = 41,828.89.
按照N=20，I/Y=12，pmt=5000，fv=0 bgn模式 为什么答案是87130呢？ 谢谢NO.PZ2015120604000011 问题如下 investor purchaseannuity many years ago. The first payment of the annuity is to receivetoy.
