what was the average rate of change of annual sales between 2001 and 2002? I am having trouble with A I got 9 million & i thought it was correct.

We will deterine the averate rate of change between 2001 and 2002 as follows:
[tex]m=\frac{250-241}{2002-2001}\Rightarrow m=9[/tex]So, the average rate of change was 9 millions,
