The population of a city increased from $23,400$ to $27,800$ between the years $2008$ and $2012$. We are asked to find the constant change in population per year during this period.

1. Problem Description

The population of a city increased from $23,400$ to $27,800$ between the years $2008$ and $2012$. We are asked to find the constant change in population per year during this period.

2. Solution Steps

First, we need to determine the total increase in population. This is the difference between the final population and the initial population.

Total increase = $27,800 - 23,400 = 4,400$

Next, we need to determine the number of years between 2008 and

2

0

1

2. Number of years = $2012 - 2008 = 4$

Now, we can calculate the constant change in population per year by dividing the total increase by the number of years.

Change per year = $\frac{4400}{4} = 1100$

3. Final Answer

The change of population per year is 1100.
