Samantha is an artist who operates her studio and gallery in town. She produces
watercolor paintings in the studio and sells them in the gallery. Give an example of an
explicit and an implicit cost that Samantha is likely to incur.
189.
Samantha quit her job teaching art at the high school and is now an artist who operates
her studio and gallery in town. She produces watercolor paintings in the studio and sells
them in the gallery. Last year at the high school she was paid a salary of $25,000. In the
operation of her small business, she spent $30,000 on supplies, $15,000 on utilities, and
$15,000 on rent. Her equipment depreciated by $3,000. How much revenue must
Samantha receive so that she doesn’t regret quitting her job as a high school art teacher?

Businesses employ resources in the production and sale of a good or service.
Accounting profit is typically used as a way of evaluating the success of a business, but
economists argue that economic profit is more relevant to determining whether a
business should continue to operate. What is the difference between these two measures
of profit? Explain why accounting profit is usually greater than economic profit.

determine how many slices you should eat.
193.
You can buy slices of pizza at $2.50 each, and you have drawn up a table that
summarizes your total cost and total benefit of purchasing up to five slices of pizza. A
coworker, looking over your shoulder, says that you should consume five slices of pizza
because the total benefit you receive is greatest at that quantity. How do you respond? Is
there any situation in which your coworker might be correct?
194.
You and a friend have each spent $8 on a movie ticket. Ten minutes into the movie, you
both decide that the movie is horrible. Your friend says that you should stay and watch
