问题如下：
An investor purchased an annutiy many years ago, he will receive $1,200 per year at the end of each of the next 40 years from this annuity. If the interest rate is supposed to be 7%, the present value of the cashflows the investor will receive is closest to:
选项：
A. $15,998.
B. $17,193.
C. $239,662.
解释：
A is correct.
N = 40; I/Y = 7; PMT = -1,200; FV = 0; CPT PV = $15,998.05
首先，这里为什么不是按永续年金来计算，因为每个四十年都会收到一笔1200。 第二，为什么PMT=-1200，收到现金，不是应该是正数的吗？NO.PZ2015120604000009问题如下 investor purchaseannuity many years ago, he will receive $1,200 per yethe enof eaof the next 40 years from this annuity.

NO.PZ2015120604000009 老師您好，我剛開始對題目的理解是每年返還1200，40年 FV不應該是48000嗎？
NO.PZ2015120604000009 $17,193. $239,662. A is correct. N = 40; I/Y = 7; PMT = -1,200; FV = 0; CPT PV = $15,998.05请问1200每年不是现金流的流入吗，每年从这年金里返回1200，为什么用负号啊1
你好！annuity不是先付年金么？为什么不用BGN而是用EN
