Question
Mr. Starch is the mayor of a small farming town, Spudville, whose primary crop is potatoes.
If the price of potatoes is P, then the townspeople will demand D(P)= 1200 – 100P
potatoes per week for their own use. The number of potatoes that will be supplied per week
by the town's potato growers is S(P)= 100P.
a. Find the equilibrium price of potatoes and the equilibrium quantity of potatoes that
will be supplied.
b. One day, Mr. Starch decides to tax his town in order to collect potatoes for his Royal
Spud Larder. The mayor required every person who consumed a potato to pay an
additional potato to the mayor as a tax. Thus, if a person wanted 5 potatoes for
himself, he would have to purchase 10 potatoes and give 5 to the mayor. When the

The mayor required every person who consumed a potato to pay an additional potato to the mayor as a tax. Thus, if a person wanted 5 potatoes for himself, he would have to purchase 10 potatoes and give 5 to the mayor. When the
price that is received by the sellers is ps, how much does it cost one of the
townspeople to get an extra potato for himself?
c. When the price paid to suppliers is ps. how many potatoes will the townspeople
demand for their own consumption? (Hint: Express P, in terms of ps and
substitute into the demand function.)
d. Since the mayor consumes a potato for every potato consumed by the townspeople,
the total amount demanded by the mayor and his town is twice the amount
demanded by the townspeople. Find the total number of potatoes demanded per
week by Mr. Starch and his townspeople when the price received by suppliers is ps.
e. Solve for the equilibrium value of ps; the equilibrium total number of potatoes
produced, and the equilibrium total number of potatoes consumed by the
townspeople.
f. The people of Spudville resented paying the extra potatoes to the mayor, and
whispers of revolution spread through the town. Worried by the hostile atmosphere,
the mayor changed the potato tax. Now, the shopkeepers who sold the potatoes
would be responsible for paying the tax. For every potato sold to a customer, the
shopkeeper would have to pay one potato to the mayor. Find the total number of
potatoes that will be consumed by the townspeople in this scenario. How much are
the townspeople paying per potato? How much do the shopkeepers get to keep from
each potato sale after paying their tax to the mayor?
