Question 150445: Maybe I have solved it will you see if I ave done it correctly? I need help.
Investing in stocks-US small companystocks have returned an average of 14.9% annually for the last 50 years. Use the present value formula...P=A(1+r)^n...
to find the amount invested today in small company stocks that would be worth $1million in 50 years, assuming that small company stocks continue to return 14.95% annually for the next 50 years.
this is not exactly the given formula but........
F=P(1+(r/n))^nt
1000000=P(1+.149/1)^50
1000000=P(1.149)^50
=1000000/(1.149)^50
=1000000/1037.531843
=$963.83 = amount to invest
