Two small towns are adjacent to one another. Town A has a population of 500 people, while Town B has a population of 1200.
Town A has a population growth rate of 4% per year. Town B’s annual growth rate is 1.75%.
When will the populations be the same? What will their populations be when they are the same?
==================
Population of town A: PA = 500 + 0.04t ---- t in years
---
Write a similar equation for town B. PB = ****************
Then, PA = PB, solve for t.
Then solve for PA & PB.
