Version A: Page 2 of 10
BONUS: 5 easy extra points.
Make sure you have completed the instructions on the front page completely and
accurately.
Part I: [30 points out of 60 total].
1. [3 pts] A small town has five (5) taxi cabs. Each of the taxi cabs has an identical supply
curve as follows:
qiS = 2×P 20
The town has 100 potential tax customers. Each of the customers has demand as follows:
qiD = 2 0.05×P
What is the equilibrium quantity of taxi rides in the town? Q*= _______________
2. [3 pts] A farmer produces two crops: Sheep and
Flowers. The flowers grow in the soil, and the sheep
graze on the land. The problem is, sheep eat the
flowers and become sick. Sheep are bad for flowers,
and flowers are bad for sheep.
On the axes, sketch what you think the farmer's PPF
might look like.

3. [10 pts] For this problem, do not worry if prices and quantities are not "realistic." Suppose
that the market for photocopies in Washington DC is perfectly competitive, and is given by
the following equations:
QD = 72 − P QS = 5P
where QD is the daily demand for copies in DC and QS is the total supply curve of all
copy stores together in DC.
a) What is the equilibrium price and quantity of copies in DC?
P*=__________ Q*=__________
Now, consider the cost schedule for Kinky's Kopies, a typical copy store in DC:
TC = 2q2 + 18 MC = 4q
where q (lower-case q) is the number of copies made by the single store.
b) What is Kinky's fixed cost? _______________
c) Assuming Kinky's behaves as a profit maximizing firm in a perfectly competitive
market, how many copies will it produce?
_______________
d) What is the total revenue of Kinky's ? __________________
e) What is the total cost for Kinky's? __________________
f) What is Kinky's average total cost (ATC) and marginal cost (MC)?
ATC =______________ MC =________________
g) What is the profit of Kinky's? __________________
h) If all of the other copy stores in this perfectly competitive market in DC have
identical cost curves and behave exactly like Kinky's Kopies, how many copy
stores will there be in long-run equilibrium?
