Students have asked these similar questions
At what output rate does the firm maximize profit or minimize loss?
What happens to a competitive firm whose cost function exhibits decreasing marginal cost everywhere? Construct a concrete cost function of this type and carry out the search for the profit-maximizing output.
Economists assume that by pursuing a strategy of cost minimization of production, most firms try to achieve profit maximization. Can you discuss the concept of an expansion path? If you can use a graph that would help me understand thank you

Assume that when the price is exactly equal to the average variable cost, the firm is indifferent between producing zero lamps and the profit-maximizing quantity. Also, indicate whether the firm will produce, shut down, or be indifferent between the two in the short run. Lastly, determine whether it will make a profit, suffer a loss, or break even at each price.
