The figure above shows demand and marginal revenue for a single price monopoly.

At any price above $ demand is elastic.

Assume production costs are constant and equal to $6.00 (i.e., AC = MC

= $6.00).

Output is  units per day at a price of $  per unit.

Profit is $ .

Consumer surplus is $  .

If this market was perfectly competitive

, output would exceed

the single-price monopoly output by 

 units.

If this is a perfectly price discriminating monopoly at a constant cost equal to $3.00

 - the lowest price charged per unit is $ .

 - the number of units sold is

 - total revenue is $ .

 - consumer surplus is $ .
