2.3.4.1c - Efficiency

Explain production at minimum average cost, factors affecting efficiency and ways to improve it.

Use c - efficiency to connect the rule to the data and decision in the question.

This matters because c - efficiency determines what can be inferred or chosen; begin with the stated conditions and keep the conclusion tied to the evidence.

Example: apply c - efficiency to one small, clearly defined case, show the key step or comparison, and explain the result in words.

Boundary: c - Efficiency is not a universal recommendation. Check the syllabus scope, assumptions, units and the limits of the evidence before generalising.
