For each of the following situations, identify the graph that most closely represents the cost behavior pattern of the cost in that situation. Some graphs may be used more than once or not at all.

a$.$ Monthly factory equipment depreciation, straight$-$line method is used

Monthly electric cost for a convenience store; $$50$ base monthly fee plus $$\mathrm{.}006$ per

b$.$ kilowatt used
