Hi,
In General A+=+P%281%2Br%2Fn%29%5E%28nt%29
A = Accumulated Amount
P= principal = 6000
r= annual rate = .03
n= periods per year = 1
t= years =
A%2FP+=+3+=+%281.03%29%5E%28t%29
log3/log(1.03) = t

Hello,
Plug this [log3/log(1.03) = t] into your scientific Calculator to get:
t=37.2 years (approx)
Got it?
