3. Suppose that the train system in the city of Vancouver (British Columbia) operates based on the data given in the table below. Price Quantity Total Cost Revenue Marginal Average Cost Marginal Revenue Cost 30 27 27 45 24 60 21 4 69 18 5 75 15 6 84 12 96 9 8 111 6 9 132 10 162 3.1. Calculate revenue, marginal revenue, average cost and marginal cost. (2 marks) 3.2. Based on the numbers you calculated in 3.1., what type of market structure where this firm operates is this?

What would the level of profit for this firm be? (2 marks) 3.4. Suppose the government intervenes in this market to maximize efficiency in this market, what approximate output would this firm supply and what approximate price would it charge? What would the level of profit for this firm be? (2 marks) 3.5. Suppose the government wants the firm being able to cover its production costs and implements a policy promoting zero profits in the market, what approximate output would this firm supply and what approximate price would it charge?
