Definitions:

Manufacturing Overhead

The sum of all costs associated with the production process that cannot be directly traced to specific products, such as maintenance expenses, factory utilities, and property taxes; it's crucial for calculating the total cost of production.

Relevant Range

The scope of business activity within which the assumptions about fixed and variable costs are valid.

Average Costs

This represents the total cost of production divided by the number of units produced, indicating the cost per unit.

Variable Production

Refers to the portion of production costs that vary with the level of output, including expenses like raw materials and direct labor.
