At this level of output, the marginal cost is $30 a bushel, average variable cost is $30.50 a bushel, and average total cost is $34.50 a bushel. (a) What is the firm’s total fixed cost? You must show your work.arrow_forwardConsider the following data: equilibrium price = $7.50, quantity of output produced 100 units, average total cost = $9, and average variable cost = $8. What will the firm do and why? = a. Shut down in the short run, because price is below average variable cost. b. Shut down in the short run, because price is below average total cost. c. Continue to produce in the short run, because price is greater than average variable cost. d.
