In the course of clearing land for a new development, the city of Scottsdale discovers an old gold mine. The marginal benefit and marginal cost of extracting and selling an ounce of gold are: MB = 360 - 30 MC = 60 A. (5 points) Suppose the city is operating on a two-year planning horizon and seeks to maximize profits from selling the gold they found. How much gold will the city extract in the first year if they fail to consider the marginal user cost (MUC)? B.

If the city uses a 3% discount rate, how much gold should they extract in each year
