1. Suppose a firm is operating at the minimum point of its short-run average total cost curve, so that marginal cost equals average total cost. Under what circumstances would it choose to alter the size of its plant?
2. Explain: In the short-run, why might a firm still operate even when there is a loss?
3. Suppose a firm is producing 1,000 units of output (Q). Its average fixed costs are $100. Its average variable costs are $50. What is the total cost (TC) of producing 1,000 units of output (Q)? It the price (P) of the good is $200, what is total revenue? What is total profit?© BrainMass Inc. brainmass.com July 20, 2018, 4:40 pm ad1c9bdddf
Fixed cost = costs that do not change no matter what quantity the firm produces
Variable cost = costs that depend on the quantity of output produced
Total cost = fixed cost + variable cost
Average cost = Total cost / quantity
1. The firm is minimizing its costs in the short run by optimizing its variable inputs such as labor. In the short run the firm cannot change its ...
