Question 1 Report
The diagram shows a firm's total revenue (TR) and total cost (TC) curves. At what point does the firm break even?
The correct answer is when total revenue equals total cost.
The break-even point is the level of output at which a firm's total revenue exactly equals its total cost, meaning the firm makes neither a profit nor a loss. On a TR/TC diagram, this is the point where the two curves intersect.
When total revenue exceeds total cost by the greatest amount, the firm is at the point of maximum profit, not break-even. The lowest point on the average cost curve identifies the most efficient output level, not break-even. The point where marginal cost begins to rise relates to diminishing returns, not break-even.
