Question
Ike's Bikes is a major manufacturer of bicycles. Currently, the company produces bikes using only one factory. However, it is considering expanding
production to two or even three factories. The following table shows the company's short-run average total cost (SRATC) each month for various level
of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.)

On the following graph, plot the three SRATC curves for Ike's Bikes from the previous table. Specifically, use the green points (triangle symbol) to plot
its SRATC curve if it operates one factory (SRATC); use the purple points (diamond symbol) to plot its SRATC curve if it operates two factories (

average total cost (LRATC) curve for Ike's Bikes 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.
