**Damon**, Thursday, June 10, 2010 at 7:29pmTwo ways to do it:

each year multiply by 1.015 (like compound interest)

1.015^n = 2

n log 1.015 = log 2

n = log 2 / log1.015 = 46.55 years

or do it the way they said to do it with continuous growth

dy/dt = .015y

y = yi e^.015 t

y/yi = 2 = e^.015 t

ln 2 = .015 t

t = 46.2
