Table 16-3
Julie plans to start a pet-sitting service. She surveyed her neighborhood to determine the
demand for this service. Assume that each person surveyed demands only one hour of
pet sitting services per period. Table 16-3 above shows a portion of her survey results.
Refer to Table 16-3. Suppose Julie's marginal cost of providing this service is constant
at $7 and she charges each customer according to his or her willingness to pay instead
of a uniform price of $7. Which of the following statements is true?
A) Julie is worse off because the demand for her services is reduced.
B) Julie has converted the consumer surplus (from a uniform price) into economic
profit.
C) Julie's customers are better off because their consumer surplus has increased.
D) Julie's has converted the producer surplus (from a uniform price) into consumer
surplus.

"Because chips and salsa are complements, an increase in the price of chips will cause
the demand for salsa to decrease. This initial shift in demand for chips results in a
higher price for chips; this higher price will cause the demand curve for chips to shift to
the right." Which of the following correctly comments on this statement?
A) The statement will be true if consumer tastes for chips and salsa do not change.
B) The statement is false because a change in the price of chips would not change the
demand for chips.
C) The statement is false because salsa is an inferior good; chips are normal goods.

complements for all consumers.

labor and capital.

Article Summary
In an attempt to get approval for a $6.3 billion merger with Office Depot, Staples met
with FTC regulators to discuss the possible sale of assets so the merger can proceed.
The Competition Bureau of the FTC had previously indicated that it would not approve
the merger as initially structured, but Staples expressed optimism that it would be able
to reach a settlement with the FTC. Critics have argued that a merger of Staples and
Office Depot will result in higher prices for office supplies.

October 14, 2015.

Staples and Office Depot may ultimately be approved by the Department of Justice and
