Find the values for 1950 and 1930.

You need to use the graph to find the population in 1930 and the population in 1950. Then, find the change in population from 1930 to 1950 and divide that by the change in time from 1930 to 1950.

????
The population of a city from 1990 to 2000 has nothing at all to do with change of population from 1930 to 1950!
