1.3.5.4a - Opportunity cost

Apply opportunity cost to business choices.

Use a - opportunity cost to connect the rule to the data and decision in the question.

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

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

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