in 2000, the u.s. population was 281 million people. in 2008, it was 305 million. what was the rate of population change per year?
Answer
Explanation:
Step1: Calculate the time - interval
The time from 2000 to 2008 is $2008 - 2000=8$ years.
Step2: Calculate the population change
The population in 2000 was 281 million and in 2008 was 305 million. The population change is $305 - 281 = 24$ million.
Step3: Calculate the rate of population change per year
The rate of population change per year is $\frac{24}{8}=3$ million per year.
Answer:
3 million per year
