Consider the following data: equilibrium price = $40, quantity of output produced = 100 units, average total cost = $47, and average variable cost = $37. What should the firm do and why?

A) Shut down in the short run, because it is taking a loss of $700.
B) Continue to produce in the short run, because price is greater than average variable cost.
