Study the supply curve given below and answer the following question.
For the supplier, when the marginal cost of producing a unit is $2, his profit is maximized. What will be his total revenue?
$8
Profit maximization occurs when MC = P. Since his profit maximization occurs at a marginal cost of $2, the market price is also $2. At this price, he would supply 4 units.
TR=P×Q=$2×4=$8
