➤ When is it valid to treat total cost as a constant like C = 100?
Treating total cost as constant is valid when costs are purely fixed within the analysis range. Use it for short-run problems, setup costs, or when variable costs are negligible. It is not appropriate if output affects materials, labor, or scale. Always state the assumption and check whether variable cost components matter.
