A monopolist has two types of customers. There are 100 of TYPE A, who will each pay up tp $10 for a single unit of the good, and 50 of TYPE B, who will each pay up to $8.00. Neither are willing to purchase additional units at any price. If it must find a uniform price what is the price? Assume that spending $80 on advertising will attract 100 more TYPE B customers. Should the monopolist advertise? If so what will happen to the price?
