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 each month for various levels of production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.)

7. Costs in the short run versus in the long run
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 each month for various levels of
production if it uses one, two, or three factories. (Note: Q equals the total quantity of bikes produced by all factories.)

Suppose Ike's Bikes is currently producing 600 bikes per month in its only factory. Its short-run average total cost is $
per bike.
Suppose Ike's Bikes is expecting to produce 600 bikes per month for several years. In this case, in the long run, it would choose to produce bikes
using one factory
On the following graph, plot the three short-run average total cost curves (SRATC) for Ike's Bikes from the previous table. Specifically, use the
green points (triangle symbol) to plot its short-run average total cost if it operates one factory (SRATC₁); use the purple points (diamond symbol) to
plot its short-run average total cost if it operates two factories (SRATC2); and use the orange points (square symbol) to plot its short-run average
total cost if it operates three factories (SRATC3). Finally, plot the long-run average total cost (LRATC) 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.
