Give the step-by-step reasoning process and then the final answer. About 450 000 people lived in Maryville in 2000. In 2005, about 467 000 people lived in Maryville. What is the average number of people added each year?
The total increase of people was counted in 2005 - 2000 = 5 years. In 5 years, there is a total of 467 000 - 450 000 = 17 000 people increase. So, each year, the average number of people added is 17 000 / 5 = 3 400.
The final answer: 3400.
