Costs in the short run versus in the long run

Scooter's Scooters is a large American manufacturer of electric scooters operating out of Lansing. 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.$)$

Suppose Scooter's Scooters is currently producing $600$ scooters per month in its only factory. Its short$-$run average total cost

is

per scooter.

Suppose Scooter's Scooters is expecting to produce $600$ scooters per month for several years. In this case, in the long run, it would choose to produce

scooters using $.$

On the following graph, plot the three SRATC curves for Scooter's Scooters from the previous table. Specifically, use the green points $($triangle

symbol$)$ to plot its SRATC curve if it operates one factory $($SRATC ${?}_1)$; use the purple points $($diamond symbol$)$ to plot its SRATC curve if it operates

two factories $($SRATC $2)$; and use the orange points $($square symbol$)$ to plot its SRATC curve if it operates three factories $($SRATC $3).$ Finally, plot

the long$-$run average total cost $($LRATC$)$ curve for Scooter's Scooters using the blue points $($circle symbol$).$

Note: Plot your points in the order in which you would like them connected. Line segments will connect the points automatically.

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.
