The different stages of production of any commodity can be said to possess high volumetric interdependence if the output produced in any one of the stages affects the output produced during the subsequent stages

The oldest hamburger chain in the United States is White Castle, which was founded in 1921 . Most of their restaurants in the early days were located in urban areas. In the 1950s they lost much of their business to McDonalds and Burger King

They were slow to respond in building restaurants on highways and in suburbs. How did the advent of the highway system in the 1950s alter residential location patterns and how might this have affected the marginal revenue product of burger chains in both urban and suburban areas. Why did sales drop off in the urban areas where White Castle had earned its initial success?

If Mr. McLean thinks the last dollar spent on bowling yields more satisfaction than the last dollar spent on hamburgers, and McLean is a utility-maximizing consumer, he should:

a. bowl less, so the marginal satisfaction from expenditures in this area will increase. b. spend more on hamburgers, so total satisfaction from that activity will increase. c. eliminate spending on hamburgers. d. bowl more and spend less on hamburgers.
