Cookies  (in dozens)	Price
20	2
8	5
0	7

18. Which of the following equations best represents the demand curve for Professor Kelly's cookies? Assume that P is the price per dozen cookies and Q is the quantity of cookies measured as dozens of cookies.

20. Students from the morning lecture learn about the cookies.  This causes the demand for cookies to increase.  Further, the price of milk falls due to a new government policy.  Notice that milk is commonly consumed with cookies, and is also an important ingredient in baking cookies.  Holding everything else constant, which of the following statements must be true?

a. Given the above information, we know that the demand curve shifts to the right causing a movement along the supply curve; the supply curve does not move.

b. Given the above information, we can conclude that the equilibrium quantity after these changes is greater than the initial equilibrium quantity while the effect on the equilibrium price after these changes is indeterminate

c. Given the above information, we can conclude that there is a shift in the demand curve to the right and a shift in the supply curve to the right: since both shifts are to the right we know that price and quantity increase in this market.

d. Given the above information, we can conclude that the model of supply and demand is not a very effective model since a model to be useful must provide unambiguous answers.

Use the information below to answer the next TWO (2) questions.

The residents of Mapleburgh really love their maple trees.  Each spring they hold a special market where the nurseries supply saplings according to the equation P = 10 + Q.  The demand for new trees is P = 40- Q.  The government of Mapleburgh does not like the annual expansion of the low quality maple groves.  It decides to limit the amount of new plants by introducing a quota of 5 trees that can be sold each year.  To implement the quota, the government requires that the nurseries purchase selling permits. (Hint: this question is about a quota where the quota is a quantity control imposed by the government.
