In the long run, Martha Mowers can assemble 300 mowers per week at a total cost of $18,000; 400 mowers at a total cost of $24,000; or 500 mowers at a cost of $35,000.
Using the red points (cross symbol), plot the long-run average total cost (LRATC) for these three levels of output (300, 400, and 500 mowers per week).
