At Jody's bakery they are currently selling 400 loafs of bread. It cost them $4,000 to buy an oven, $2,000 for flour and salt at this
level of production, $800 to buy a computer for administrative work, and $40,000 to lease a building for the bakery for a year. What
is this bakery's average variable cost?
Question
Costs in the short run versus in the long run
What I really need help is to calculate the LRACT. I don't know how to do it.
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: QQ equals the total quantity of bikes produced by all factories.)
