Definitions:

Average Total Cost

The per unit cost of production, calculated by dividing the total costs by the quantity of output produced.

Average Variable Cost

The total variable costs (costs that change with the level of output) divided by the total output, indicating the cost of producing one more unit.

Marginal Cost

The increase in total cost that arises from producing one additional unit of a good or service, a critical concept in economic analysis for decision-making.

Selling Price

The amount for which a product or service is sold to the customer.
