Question

Average rate of change T 2016 years 120 N # of employees T 2020 years 150 N # of employees

Answer 1

To find the average rate of change, divide the difference on the number of employees over the difference in time.

The difference on the number of employees is:

`150-120=30`

The difference on time (in years) is:

`2020-2016=4`

Then, the average rate of change of the number of employees over time, is:

`(30)/(4)=7.5\text{ employees per year}`
