Compound annual interest (college algebra)

I need help with this with steps :

If you deposit $1000 at 8% compounded annually, how long will it take for your money to triple?

I know there's a formula for this A = P (1 + r/n)^nt but I don't know how to apply it

3000 = 1000[1 + .08/1]^(1*t)

3 = 1.08^t

ln 3 / ln 1.08 = t

14.274914586003189321592765022908 = t

14.27 years = t
