This module serves as an introduction to mixed costs. Distinctions between fixed and variable costs are important.

Activity changes outside the relevant range can result in increases in either fixed or variable costs.After you have read the assigned textbook chapter,  enter this forum to describe how the firm where you work, or any business firm, distinguishes between fixed and variable costs.
