You can
put this solution on YOUR website!Henry invested $12,000 in a new restaurant. When the restaurant was sold 2 years later, he received $27,000. Find his average annual return by solving the equation 12,000(1+r)^2=27,000.
-------------------------------
I think you want to solve for "r":
12,000(1+r)^2=27,000
(1+r)^2 = 27/12 = 9/4
1+r = 3/2
r = 1/2 or 0.5
-------------
So the average return was 0.5*12000 = $6000.00
