Answer: 101 people
Explanation:
To find the increase in population between 2015 and 2016, we need to know the population density in 2015. We can find this by multiplying the land area by the population density:
84.4 square miles * 22.5 people per square mile = 1,899 people
This means that in 2015, there were 1,899 people living in Westville.
The increase in population between 2015 and 2016 is:
2,000 people - 1,899 people = 101 people
Therefore, the population of Westville increased by 101 people between 2015 and 2016.
