Question

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.
C) Susie would buy more massages and more rounds of golf,as predicted by the substitution effect.
D) Susie would buy more massages and fewer rounds of golf,as predicted by the substitution effect.

Answer 1

Answer:

D) Susie would buy more massages and fewer rounds of golf,as predicted by the substitution effect.

Explanation:

Let's check the utility that Susie gets from consuming these products.

The second round of golf gives her 20 units of satisfaction at $20 = 20/20 = 1

The third massage gives her 30 units of satisfaction at $30 = 30/30 = 1

But now the price the price for massage has come down to $15. The ratio of their prices would be

20/15 = 1.333

1.3 is greater than 1

So she should substitute golf for massages
