An investor needs $18000 in 20 years; a finance company is offering 6% compounded monthly. How much should they invest now?

compound Interest formula: A=P(1+r/n)^nt, P=initial investment r=interest rate, n=number of compounding periods per year, A=amt after  t- years
For given problem:
P=?
r=.6%
n=12
t=20
A=8000

8000=P(1+.06/12)^12*20
8000=P(1+.005)^240=P(1.005^240=3.3102
P=8000/3.3102=2416.77
 How much should they invest now?$2416.77
