The statement is false because a change in the price of apples would not change the demand for apples.

"Because apples and oranges are substitutes, an increase in the price of oranges will cause the demand for apples to increase. This initial shift in demand for apples results in a higher price for apples; this higher price will cause the demand curve for apples to shift to the right." Which of the following correctly comments on this statement? The statement is false because oranges are inferior goods; apples are normal goods. The statement is false because a change in the price of apples would not change the demand for apples. The statement is false because one cannot assume that apples and oranges are substitutes for all consumers. The statement will be true if consumer tastes for apples and oranges do not change.

decrease in demand; increase in quantity demanded

A(n) ________ is represented by a leftward shift of the demand curve while a(n) ________ is represented by a movement along a given demand curve. decrease in demand; increase in demand decrease in demand; increase in quantity demanded increase in demand; decrease in quantity demanded decrease in quantity demanded; decrease in demand

The demand for gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would increase.

An increase in input costs in the production of electric automobiles caused the price of electric automobiles to rise. Holding everything else constant, how would this affect the market for gasoline-powered automobiles (a substitute for electric automobiles)? The demand for gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would decrease. The demand for gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would increase. The supply of gasoline-powered automobiles would increase and the equilibrium price of gasoline-powered automobiles would decrease. The demand for gasoline-powered automobiles would decrease because consumers could afford to buy fewer gasoline-powered automobiles.

the equilibrium price of MP3 players will increase; the equilibrium quantity will decrease.

Assume that the demand curve for MP3 players shifts to the right and the supply curve for MP3 players shift to the left, but the supply curve shifts more than the demand curve. As a result the equilibrium price of MP3 players will increase; the equilibrium quantity will decrease. the equilibrium price of MP3 players may increase or decrease; the equilibrium quantity will decrease. the equilibrium price of MP3 players will decrease; the equilibrium quantity will increase. both the equilibrium price and quantity of MP3 players will decrease.

The demand for Blu-ray players would increase and the equilibrium price of Blu-ray players would increase.

Positive technological change in the production of LCD televisions caused the price of LCD televisions to fall. Holding everything else constant, how would this affect the market for Blu-ray players (a complement to LCD televisions)? The demand for Blu-ray players would increase and the equilibrium price of Blu-ray players would decrease. The demand for Blu-ray players would decrease because consumers could afford to buy fewer LCD televisions and Blu-ray players. The demand for Blu-ray players would increase and the equilibrium price of Blu-ray players would increase. The supply of Blu-ray players would increase and the equilibrium price of Blu-ray players would decrease.
