Students have asked these similar questions
1) What is total fixed cost at the profit-maximizing quantity?
2) Below what price will the firm shut-down?
3) What are operating losses / profit (If the firm does not shut-down)?
Perfect Competition
MC - Marginal Cost
MR - Marginal Revenue
ATC - Average Total Cost
Refer to the figure above. If this firm is producing the profit-maximizing quantity and selling it at the profit-maximizing price, the firm's profit will be:
$240
$160
$80
$60
Perfect Competition
MC - Marginal Cost
MR - Marginal Revenue
ATC - Average Total Cost
Refer to the figure above. If this firm is producing the profit-maximizing quantity and selling it at the profit-maximizing price, the firm's total revenue will be:
$240
$90
