Consider an individual that can consume two goods, bus tickets and coffee, and who
always has positive marginal utility for both goods. Suppose a person currently
buys 10 bus tickets and 10 cups of coffee per week. She is indifferent between this
consumption bundle and the bundle consisting of 9 bus tickets and 12 cups of coffee.
From this, we can infer that
(a) she would prefer giving up one bus ticket to get three extra cups of coffee.
(b) she is indifferent between her current bundle and a bundle with one less bus
ticket and one extra cup of coffee.
(c) she prefers one extra cup of coffee to one extra bus ticket.
(d) None of the above is correct. correct answers A

(c) the opportunity cost of an hour of leisure falls.
(d) above a certain wage fewer hours are supplied. correct answers D
