Note that the quantity is in millions of riders.The state of Colorado requires oil and gas companies who use fracking techniques to retune the land to its original condition after the oil and gas extractions. Table 12.9 shows the total cost and total benefits (in dollars) of this policy. Calculate the marginal cost and the marginal benefit at each quantity (acre) of land restored. See Production. Costs and Industry Structure if you need a refresher on how to calculate marginal costs and benefits.
