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.) Number of Factories Average Total Cost (Dollars per bike) Q = 100 Q = 200 Q = 300 Q = 400 Q = 500 Q = 600 1 220 160 120 160 240 360 2 290 200 120 120 200 290 3 360 240 160 120 160 220 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 . 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
