A manufacturing company that produces tires has the following production function and marginal product function.

The machine that molds the tires costs $100. Each unit of raw rubber cost the firm $3. The firm sales each tire at a price of $50. The production process produces a waste that is dumped into a nearby river which kills fish. Because of the smaller fish population, this financially harms local fishermen. More specifically, for every unit of raw rubber the tire manufactory uses it reduces the profits of local fishermen by two dollars.
