The vertical axis on each graph represents total cost and the horizontal axis represents the level of activity (volume). Required: 1. For each of the following situations, identify the graph that illustrates the cost behavior pattern involved. Any graph may be used more than once. a.

Rent on a factory building donated by the city, where the agreement calls for a fixed fee payment unless 200,000 labor-hours or more are worked, in which case no rent need be paid. e. Cost of raw materials, where the cost starts at $7.50 per unit and then decreases by 5 cents per unit for each of the first 100 units purchased, after which it remains constant at $2.50 per unit. f. Salaries of maintenance workers, where one maintenance worker is needed for every 1,000 hours of machine-hours or less (that is, 0 to 1,000 hours requires one maintenance worker, 1,001 to 2,000 hours requires two maintenance workers, etc.). g.
