Scooter's Scooters is a large American manufacturer of electric scooters operating out of Mesa. Currently, the company produces all of its scooters using a single manufacturing facility, its factory in town. Recently, management has been considering expanding operations to one or two additional factories. The following table presents the manufacturer's monthly short-run average total cost (SRATC) for various levels of production if it operates out of one, two, or three factories. (Note: Q equals the total quantity of scooters produced by all factories.) Average Total Cost (Dollars per scooter) Number of Factories Q = 50 Q = 100 Q = 150 Q = 200 Q = 250 Q = 300 1 180 100 80 120 200 360 2 270 150 80 80 150 270 3 360 200 120 80 100 180 Suppose Scooter's Scooters is currently producing 50 scooters per month in its only factory. Its short-run average total cost is $ per scooter. Suppose Scooter's Scooters is expecting to produce 50 scooters per month for several years. In this case, in the long run, it would choose to produce scooters using one factory On the followin symbol) to plot two factories three SRATC curves for Scooter's Scooters from the previous table. Specifically, use the green points (triangle if it operates one factory (SRATC); use the purple points (diamond symbol) to plot its SRATC curve if it operates two factories (three factories se the orange points (square symbol) to plot its SRATC curve if it operates three factories (SRATC3). Finally, plot the long-run average total cost (LRATC) curve for Scooter's Scooters using the blue points (circle symbol). In the following table, indicate whether the long-run average cost curve exhibits economies of scale, constant returns to scale, or diseconomies of scale for each range of scooter production. Range Between 150 and 200 scooters per month More than 200 scooters per month Fewer than 150 scooters per month Economies of Scale Constant Returns to Scale Diseconomies of Scale
