Supply curve in the short run for a perfectly competitive firm is

  • MC curve
  • along the MC but above the minimum point of AVC curve
  • along the MC but below the minimum point of AVC curve
  • along the MC but above AVC curve

 

For a perfectly competitive firm, Q= 70; P=$5; AFC = $2; AVC = $7. What is the profit/ loss of the firm?
