The math class may illuminate economics, and the economics class can motivate mathematics. If the classes conflict, they are substitutes. b. tennis balls and a tennis racket Tennis balls and a tennis racket are both needed to play a game of tennis, thus they are complements. c. steak and lobster Foods can both complement and substitute for each other. Steak and lobster can compete, i.e., be substitutes, when they are listed as separate items on a menu. However, they can also function as complements because they are often served together. d. a plane trip and a train trip to the same destination Two modes of transportation between the same two points are substitutes for one another. e. bacon and eggs Bacon and eggs are often eaten together and are, therefore, complementary goods. By considering them in relation to something else, such as pancakes, bacon and eggs can function as substitutes. 6. Suppose that a consumer spends a fixed amount of income per month on the following pairs of goods: a. tortilla chips and salsa; b. tortilla chips and potato chips; c. movie tickets and gourmet coffee; d. travel by bus and travel by subway. 7. If the price of one of the goods increases, explain the effect on the quantity demanded of each of the goods. In each pair, which are likely to be complements and which are likely to be substitutes? a. If the price of tortilla chips increases, the demand for both goods will fall, assuming they are complements. The demand curve for salsa will shift to the left. b. If the price of tortilla chips increases, the demand for tortilla chips will fall and the demand for potato chips will rise, assuming they are substitutes. The demand curve for potato chips will shift to the right
