Question 436853
 I have an investment of $1500. After 4 years, it becomes $1700. The number of compounding periods are 360. What is my rate? 
--------------
If in 4 years you are compounding 360 times, you are
compounding 90 times each year.  That is "n" in the
compounding formula.
------------------------------
A(t) = P(1+(r/n))^(nt)
-----
1700 = 1500(1+r/90))^(90*4)
-------------------------
 17/15 = (1+(r/90)^(360)
---
Take the 360 root of both sides to get:
1+(r/90) = 1.000348
r/90 = 0.000348
rate = 0.0313
rate = 3.13%
