Suppose you invest your money into an account that pays 4.0% per year compounded quarterly. How long (in years) will it take for your money to triple?

Round your answer to one decimal place.

I know I use this...
A=P(1+r/n)^nt

But to go from there and get an answer, so confused. Thank you for your help!
