The local government projects that the town will grow at a constant rate of thirty-two percent per year. at this rate, how many years will it take the town's population to be five times its current size?

Let's say that the current population is x. The question is then when will it be 5x?

let's see:

after the first year it will be 1.32x
after the second year it will be 1.32(1.32x) =1.74x
after the third year it will be 1.32(1.32(1.32x)) =2,29x
after the forth year it will be 1.32(1.32(1.32(1.32x)))=3x
after the firth year it will be 1.32(1.32(1.32(1.32(1.32x=4x
after the sith year it will be 1.32(1.32(1.32(1.32(1.32(1.32x=5,28x

so the answer is : after 6 years.
