curve. Now assume that the price of CDs rises but the price of DVDs falls. How can
you show that Anne is made better off by these price changes?
A) Show that the price changes shift Anne’s budget line outward; the budget line is
tangent to a higher indifference curve.
B) Show that the price changes move Anne along her budget line to a higher
indifference curve.
C) Show that Anne can afford to buy the optimal combination of DVDs and CDs at
their original prices; then show that Anne can now reach a higher indifference curve.
D) Show that Anne can now afford to buy more DVDs, which give her greater utility
than CDs.
Assume that both the demand curve and the supply curve for MP3 players shift to the
right but the supply curve shifts more than the demand curve. As a result
A) both the equilibrium price and quantity of MP3 players will decrease.
B) the equilibrium price of MP3 players will decrease; the equilibrium quantity will
increase.
C) the equilibrium price of MP3 players may increase or decrease; the equilibrium
quantity will decrease.
D) the equilibrium price of MP3 players will increase; the equilibrium quantity will
decrease.
