Assume that Anne has $300 to spend on DVDs and CDs. Her optimal consumption of
DVDs and CDs is illustrated by a tangency between a budget line and an indifference
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?

tangent to a higher indifference curve.

indifference curve.

their original prices; then show that Anne can now reach a higher indifference curve.
