Answer :
a) Yes, $67 exceeds the loss—minimizing output.
Using the MR
They will produce 9 units.
Profits per unit = $67 - $50 = $17
Total profit = $153.
(b) Yes, $42 exceeds the loss—minimizing output.
Using the MR
They will produce 6 units
Loss per unit is = $42 - $47.50 = $5.50
Total loss = $33 (= 6 x $5.50), which is less than the total fixed cost of $60.
c) No, because $33 is less than AVC. If it did produce, the quantity will be 4—By producing 4 units, it would lose $78 [= 4 ($33 - $52.50)]. and if they didn't produce, it would lose only the total fixed cost of $60.
