8) Susie buys two goods: rounds of golf and massages. Suppose that the price of a
round of golf is $20 and the price of a massage is $30. In a typical week, Susie will play
two rounds of golf, getting 20 units of satisfaction from the second round. She normally
buys three massages each week, with the third giving her 30 units of satisfaction. If she
were to buy a fourth massage in a week, it would give her 20 units of satisfaction. If the
price of massages is reduced to $15, which of the following outcomes might we expect
to occur?
A.Susie would leave her consumption choices unchanged because of diminishing
marginal utility in the consumption of massages.
B.Susie would buy more massages and fewer rounds of golf, as predicted by the income
effect.
