Susie receives an allowance from her parents of $10 per week. She spends her entire

Kylie spends her income of $150 per week on two goods: movies (which cost $5 each)
and books (which cost $10 each). At her current level of consumption, the marginal
utility from the last movie consumed is 20 and the marginal utility from the last book
consumed is 30. Is Kylie maximizing her utility? Why or why not? If not, what should
Kylie do to achieve a higher level of utility?

In many large American cities it is common to witness private motorists pulling up to
municipal bus stations and allowing perfect strangers to ride into downtown with them

drivers. Using the concept of elasticity of demand and total revenue explain why public
transit authorities might be concerned with this practice.
Assume that an employer discovers that the marginal revenue product of the last two

operating in a purely competitive market in both the output that he sells and the labor
that he hires. What would you advise this employer to do and why?
In cases where a life insurance policy owner is not the same person as the insured,
insurance companies often require that such purchases be for those with an "insurable
interest". For life insurance policies, close family members and business partners will
usually be found to meet this test. In this case the purchaser is demonstrating that they
would suffer an economic loss if the insured were to die. What economic argument
could be made for why insurance companies would make such a restriction when it
seems there might be a market for life insurance to people who wish to insure others for
whom there is not such "insurable interest"?
What relationship is shown by a demand curve?
What role do business firms play in output markets and in factor markets?
