In 2012, the population in a town was 8,000 people. In 2017, the population was 11,400. What was the percent increase in the population?

assume male population = x then female = 8000 - x

New male pop = 1.1*x, New female pop = 1.08*(8000-x), new total pop = 1.09*8000

1.09*8000 = 1.1*x + 1.08*(8000-x)

> 8720 - 8640 = 0.02x

>x = 4000

no not all of them.

step-by-step explanation:

some of them have a square base.
