Assume quantities must be in integers. The following table gives a monopolist's demand schedulefor both students and profs. (Profs demand begin to demand 3 units when the price drops to $11.Students begin to demand 3 units when the price drops to $6). The monopolist faces a marginalcost of $2.50

If the monopolist can charge one price for students and a different price for profs, what are its total revenues?
