The question supplies a schedule of the market demand curve (price at each quantity) and the total cost at each quantity for a monopoly firm. The schedule itself was not included with this stem, so exact numbers cannot be filled in without fabricating data (which is not permitted). The correct step-by-step procedure is:
a) MR and MC schedules
- Total Revenue at each output: .
- Marginal Revenue: (change in TR when output rises by one unit).
- Marginal Cost: (change in TC when output rises by one unit).
b) Quantity where MR = MC
- Compare the MR and MC columns row by row; the output level at which MR equals MC (or MR is just above MC before falling below it) is the profit-maximising quantity.
c) Equilibrium quantity and price
- The equilibrium quantity is the MR = MC output found in (b). …
