In 2007, the US population was 302 million people. In 2012, and 314 million. What was the rate of the population change per year?
314 - 302 =12 / 5 = 2.4,
the population grows 2.4 percent of people a year.
The correct answer is:
2.4 million.
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.
