To find the average growth over 5 years based on the given data, we start with the information that the town's population has grown by 600 people over 2 years.
We first determine the average annual growth:
- Average annual growth = Total growth over 2 years / 2
- Average annual growth = 600 people / 2 years = 300 people per year.
Next, we calculate the expected growth over 5 years:
- Growth over 5 years = Average annual growth * 5 years
- Growth over 5 years = 300 people/year * 5 years = 1,500 people.
The correct answer is 1,500 people.
