3) (10 points) Conigan Box Company produces cardboard boxes that are sold in bundles of 1000 boxes. The market is highly competitive, with boxes currently selling for $100 per thousand. Conigan's total and marginal cost curves are: TC = 3,000,000 + 0.001Q2 MC = 0.002Q where Q is measured in thousand box bundles per year. a. Calculate Conigan's profit maximizing quantity. Is the firm earning a profit? b. Analyze Conigan's position in terms of the shutdown condition. Should Conigan operate or shut down in the shortrun?

6) (15 points) A country which does not tax cigarettes is considering the introduction of a $0.40 per pack tax. The economic advisors to the country estimate the supply and demand curves for cigarettes as: QD = 140,000-25,000P QS = 20,000 + 75,000P, where Q = daily sales in packs of cigarettes, and P = price per pack. The country has hired you to provide the following information regarding the cigarette market and the proposed tax. a. What are the equilibrium values in the current environment with no tax? b. What price and quantity
