Work Step by Step

In the double bar graph, 2009 is showing the greatest difference in sales between super unleaded and supreme unleaded gasoline. Super unleaded rises to 400 Multiply 400 by 1000 because the label on the left side of the graph says in thousands i.e. 400,000 while Supreme unleaded rises between 100 and 200. So it rises to 150 multiply by 1000 = 150,000 Difference between super unleaded and supreme unleaded for 2009 = 400,000 - 150,000 = 250,000 gal.
