the population of a city increased from 24500 to 41600 between 2003 and 2012 . find the change of population per year if we assume the change was constant from 2003 and 2012.
We'll start by subtracting; 41,600-24,500= 17,100 Then we'll divide 17,100 by 9 because there is a 9 year difference between 2003 and 2012. 17,100/9=1,900
