A number of scattergraphs displaying cost behaviour patterns are shown below. The vertical axis on each graph represents total cost. and the horizontal axis represents the level of activity (volume). a. Charges for data usage on a smartphone plan-o flat fixed charge for the first 500MB. plus a variable cost per megabyte for usage above 500MB. b. Wages for software development staff, all of whom are paid a fixed monthly salary. c. Licensing fees paid to the provincial government to operate dog sled tours.
