Parents wish to have $160,000 available for a​ child's education. If the child is now
7 years​ old, how much money must be set aside at 6 % compounded semiannually to meet their financial goal when the child is​ 18?

Respuesta :

A=p (1+I/k)^kn

A future value 160000
p present value ?
I interest rate 6/100=0.06
K compounded semiannual 2
T time 18-7=11years

160000=p (1+0.06/2)^(2Ă—11)
Divide each side by (1+0.06/2)^(2Ă—11)
P=160,000Ă·(1+0.06Ă·2)^(2Ă—11)
P=83,502.8

Hope it helps:-)
