yay, doubling time the equation is [latex]A=P(2)^frac{t}{d}[/latex] A=final amount P=initial amount t=time elapsed in years d=doubling time in years ok A=A P=100 d=8yrs t=40yrs so [latex]A=100(2)^frac{40}{8}[/latex] [latex]A=100(2)^5[/latex] [latex]A=100(32)[/latex] [latex]A=3200[/latex] there will be $3200 in the account after 40 years
