Three alternative designs have been created by The Atlas Company, Inc. for use on their assembly line. The fixed costs and variable costs are shown in the table below. For production volumes from 0 - 200,000 units, determine which design should be chosen. Depict this both mathematically and graphically. Label the crossover points, the axis, the lines and the areas where each design would be selected. Design Fixed Cost Variable Cost ($/unit x) A $20,000 $45/x B $70,000 $20/x $120,000 $15/x
