Question

"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?" (What equation do I need to do? You can answer the question, but I need to show work as well. Thanks)

Answer 1

305 million - 281 million=24 million
24 million /8 years=3 million
3 million per year
