28. Here you see the demand curve and marginal revenue curve faced by a monopolist. The monopolist has recently experienced an increase in its marginal costs, from MC1 ($20) to MC2 ($40).
Part 1: Using the double drop line tool, select the price-quantity combination that the monopolist would choose when facing Marginal Cost 1 and label it profit maximization 1.
Part 2: Using the double drop line tool, select the price-quantity combination that the monopolist would choose when facing Marginal Cost 2 and label it profit maximization 2.
Part 3: Using the quadrilateral tool, shade in the area that represents the lost revenue for the monopolist due to the increase in marginal costs. Label this as Lost Revenue.
Part 4: Using the quadrilateral tool, shade in the area that represents the gained revenue for the monopolist due to the increase in marginal costs. Label this as Gained Revenue.
