Answer 2

The correct answer is:

2.4 million.

Step-by-step explanation:

To find the rate of change, first we find the amount that the population grew in the time period:

314-302 = 12

Now we calculate the number of years:

2012-2007 = 5

Divide the amount of change by the number of years:

12/5 = 2.4

The population grew by 2.4 million people per year.
