If the population of a town grew 15% up to 76,894, what was the population lest year?

Let's first find the equation to find what the population went up to. X, will be the population of last year.

1.15x=76,894

Now, we need x by itself, so we need to divide both sides by 1.15.

76,894:1.15≈66,864

There are decimals, but for this problem, hae. 3478 of a person would not fit.

We can check our answer.

66,864*.15=10,029.6

10,029.6+66,864=76,893.6 (rounds up to 76,864)

So the population of the town last year was about 66,864 (66,864.3478) people.
