It also stimulates production of IGF-1. GH is used as a prescription drug in medicine to treat children's growth disorders and adult growth hormone deficiency. In the United States, it is only available legally from pharmacies, by prescription from a doctor.
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.
Average total cost. Average total cost (ATC) is the total cost per unit of output. Itâs determined by dividing the total cost equation by the quantity of output. Using the total cost equation. average total cost equals. where q is the quantity of output produced. Marginal cost always intersects the minimum point on the average total cost curve. Thus, average total cost initially decreases, and then begins to increase, resulting in a U-shaped curve.
