Question 95510
Suppose you make a principal investment (P) of $5000 in the stock market after two years (t) your stocks have an accured value (A) of $20,000. What is the annual rate of return based on compound interest. A(t)=P(1+r/n)^(nt)

----------------------
20000= 5000(1+r)^(1*2)
4 = (1+r)^2
Take the square rt of both sides
1+r = 2
r = 1
--------
Yes, that's 100%
