40) Refer to Figure 6.10. Kyle would increase his consumption of turkey sandwiches from 5 to 7 per week
if their price fell from $8 to $6. This illustrates the idea of
A) consumer surplus.
B) the law of diminishing marginal utility.
C) cross–price elasticity of demand.
D) technical efficiency.

41) The marginal utility of the first cup of coffee that Tom drinks in the morning is worth $2.00. The
marginal utility of the 9th cup of coffee he drinks is positive while the marginal utility of the 10th cup of
coffee he drinks in the morning is worth $0. This implies that at a price of $0, Tom would drink
A) zero cups of coffee per morning.
B) at most 10 cups of coffee per morning.
C) more than 10 cups of coffee per morning, but the actual number is indeterminate from this
information.
D) an infinite number of cups of coffee each morning.

42) For Matthew, the marginal utility of the 9th soda in a day is positive and the marginal utility of the
10th soda in a day is zero. This
A) implies that Matthew’s demand curve for sodas per day will become upward sloping at 10 sodas per
day.
B) is impossible because each additional unit of consumption of any good must provide positive marginal
utility.
C) implies that at a zero price Matthew’s demand curve will intersect the quantity axis at 10.
D) implies that Matthew maximizes utility by consuming 9 sodas per day.
