22.              Lisa Beth loves bananas and derives 10 utils of total utility eating the first one. When she
                            consumes a second banana, her total utility increases to 15 utils. Eating the third raises
                            her total utility to 18 utils. Economists reading her likes and dislikes conclude that

a.because the total utility of the first is 10, she is better off consuming that one and no
more

b.because the marginal utility of the third banana is 18/3 = 6 utils, she would be better
off adding that third to consumption because 6 utils is still better than zero

c.the marginal utility of the second banana is 8 utils, which means she should not eat it

d.the marginal utility of the first banana is zero, even though total utility is 10 utils
because at zero bananas, total utility is zero

e.the marginal utility of the third banana is 3 utils, which conforms to the law of
diminishing marginal utility

23.              On Thanksgiving, Jake’s mother gives him a huge platter of food. If Jake were to keep

a.the same as his total utility

a.increase the marginal utility you derive from that sofa

b.increase your consumer surplus

25.              Utility theory assumes that marginal utility of a good

a.increases as an individual consumes more of the good

b.decreases as an individual consumes more of the good

c.is greater than total utility as long as total utility is greater than zero

d.is constant as long as the individual derives utility from the good

e.is greater than total utility as long as marginal utility is greater than zero

26.              Bonnie gets her hair cut at her usual salon and is very happy with the results. Later that
                            afternoon, she goes to the mall and sees that a hair salon is giving away free haircuts only

a.marginal utility of another haircut would be zero or negative

b.marginal utility of another haircut would increase

c.marginal utility of another haircut would be zero or positive

d.total utility of both haircuts would be zero or negative

e.total utility of both haircuts would be higher than just one haircut

27.              When marginal utility is positive, then total utility is

28.              When marginal utility is negative, then total utility is

a.positive

b.decreasing

c.zero
