<PRE><B>Question 983491</B>
 How long will it take an investment of 12,500 to earn $125 
in interest at 4% per year ( use bankers interest)
---------
A(t) = P(1+(r/n))^(n*t)
---------
12500 + 125 = 12500(1+(0.04/1))^(1*t)
---------
1.01 = 1.04^t
----
t = log(1.01)/log(1.04)
---
t = 0.2538 years = 3.04 months
