Solution
Calculate the Future value of the Investment
FV = PV ( 1 + r )n
FV = Future Value of investment
PV = Present Value Of Investment
r = Annual Interest Rate
n = End of the year
So as per this problem :
FV = PV(1 + r )n
PV = $5000
r = 6% or 0.06
n = 18 years
FV = PV (1 + r)n
= 5000 ( 1 + 0.06 ) 18
= 5000 ( 1.06 ) 18
= ( 1.06)18 = 1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06*1.06
= 2.85433
= 5000 * 2.85433
= $14271.50
