Suppose the monopolist can price discriminate after the 4th unit. That is, the first four units are sold at a price of $27. If they want to sell a 5th unit, they charge $27 from the first four units, and $26 from the 5 th unit (for a total revenue of 274+26=134 ). If they want to sell 7 units, their revenue will be 274+26+25+24=$183, and so on. How many units does this price discriminating monopolist sells (if indifferent between two quantities, assume they sell the LARGER quantity)
