Try a question

From “Scarcity and choice”.

Questions are in English, like the exam. Every answer comes with an explanation.

Maya can spend Saturday working (earning $80), revising for exams, or at the beach. She chooses to revise; she would otherwise have worked. What is the opportunity cost of revising?

  1. AThe beach and the $80
  2. BNothing, because revising is free
  3. CThe cost of her textbooks
  4. DThe $80 she could have earned
Show the answer

D. The $80 she could have earned

Opportunity cost is only the next best alternative, not every alternative.
