Q3 (10 points) Saved Suppose the market for cars has two segments, businesses and home users. The demand curve for cars by businesses is p = 120 - 40q , where q is the quantity of cars demanded by businesses with the price is p . The demand curve for cars by home users is p = 40 - 10q,, where q, is the quantity of cars demanded by home users when the price is p. Both businesses and home users will never demand negative amounts of cars, so for sufficiently high prices, the demand will be 0.
