Question 199909
I am assumeing that "r" is the average annual revenue, so I will solve for "r":
12,000(1 + r)^2=27,000
12,000/12,000(1+r)^2=27,000/12,000 [Isolate the r-variable]
(1 + r)^2=2.25
(sqrt(1+r)^2=sqrt(2.25)
1+r=1.5
r=1.5-1
r=0.5
Check by plugging 0.5 back into the original equation and solve.
