Question 304576: Henry invested $12,000.00 in a new restaurant. When the restaurant was sold two years later, he received, $27,000.00. find the average annual return by solving the equation 12,000 (1 + r)^2=27,000

You can put this solution on YOUR website!
12,000 (1 + r)^2=27,000
%281+%2B+r%29%5E2+=+27000%2F12000+
%281+%2B+r%29%5E2+=+27%2F12+
Take the square root of both sides:
+1%2Br+=+sqrt%2827%2F12%29+
+r+=+sqrt%2827%2F12%29-1+
r = 0.50 (or, 50%)
