Marginal cost is the change in total cost when another unit is produced; average cost is the total cost divided by the number of goods produced. Distinguish between marginal and average costs. The marginal cost is the cost of producing one more unit of a good.
It is clear from the diagram (13.9), that the long run marginal cost curve and the long run average total cost curve show the same behavior as the short run marginal cost curve express with the short run average total cost curve.he marginal cost of the second unit is the difference between the total cost of the second unit and total cost of the first unit. The marginal cost of the 5th unit is $5. It is the difference between the total cost of the 6th unit and the total cost of the, 5th unit and so forth.
