Set up a cost-volume graph. Volume should range from zero to 24,000 units (in 4,000-unit increments), and cost should range from zero to \($24,000\) (in \($4,000\) increments). Plot each of the following groups of cost data using different marks for each group. After completing the graph, indicate the type of cost behavior exhibited by each group.

Volume (applicable to each group) 2,000 6,000 10,000 20,000 Group A Costs Group B Group C Costs Costs $ 6,600 $ 2,400 $8,000 9,800 7,000 8,000 13,000 12,000 8,000 21,000 24,000 8,000
