At what output does a perfectly competitive firm maximize its profit?
when marginal cost equals average fixed cost
when average total cost equals average revenue
when total revenue equals total variable cost
when marginal cost equals marginal revenue
According to marginal analysis, a perfectly competitive firm will produce an output level where what is true about its Marginal Revenue and its Marginal Cost?
A perfectly competitive firm produces the level of output at which MR=MC on the rising portion of the firm’s marginal cost curve. At that output level, it has the following costs and revenues:
TC = $830,000
VC = $525,000
TR = $428,000
Given that the firm produces the level of output at which MR=MC, calculate the amount of profit (loss) this firm earns.
is it Profit=TR-TC?
