Answer:
The population in three years will be 6400.
Step-by-step explanation:
Given: A town had a population of 3600 three years ago. It is currently 4800.
To determine: What will the population be three years from now if the rate of population growth has been constant over the years and has been compounding annually?
In three years, the population grew from 3600 to 4800. That is a 1200 percent increase over a three-year period.
As a result, the rate of growth over the last three years has been 1200/3600 = 1/3.
The rate of growth over the next three years will also be the same.
As a result, the population will increase from 4800 to 1600 by 1/3 * 4800 = 1600.
As a result, the population in three years will be 4800 + 1600 = 6400.
