Supply and Demand Problem Set[1]

Use the following graph to answer questions 1 through 3:

Plot the following Price and Quantity combinations: (4, 8), (1, 2), (5, 10)

Is your graph more likely to be a demand curve or a supply curve? Why?

Using the equation of a line, and P for price and Q for quantity, what is the algebraic formula of this curve?

Use the following graph to answer questions 4 and 5:

Plot the following Price and Quantity combinations. Note that the points are given in the format (Quantity, Price).

(0, 50), (2, 40), (4, 30), (6, 20), (8, 10)

Using the equation of a line, what is the algebraic formula of this demand curve?

Use the following information to answer questions 6 through 10:

Price: $10, Quantity:

Use the following graph to answer questions 11 through 14:

Let's call the original demand curve (from Question 4) D1 and the new demand curve (from Questions 6-10) D2. Plot both of the demand curves on the graph above.

Use the formulas for the two demand curves to compute the quantity demanded shown by each curve at a price of $34.

Demand Curve D1: Price: $34, Quantity:
Demand Curve D2: Price: $34, Quantity:
Describe what has happened to demand in this problem.

Use the following information to answer questions 15 and 16:

Use the following two equations for the demand and supply curves to compute the equilibrium price value.

Demand curve:

Supply curve:

What is the value of the equilibrium price?

What is the equilibrium quantity?

Use the following information to answer questions 17 and 18:

Suppose Congress cuts personal income tax rates.

Draw a simple supply and demand graph to show how this would affect the market for refrigerators.

Why does this shift occur? How does that affect the equilibrium price and quantity? Explain.

Use the following information to answer questions 19 and 20:

Suppose that scooter workers accept a pay cut of 2 dollars per hour.

Draw a graph to show how this would affect the market for scooters.

Why does this shift occur? How does that affect the equilibrium price and quantity? Explain.

Definition Video Definition Point where the demand and supply curves intersect. At the equilibrium price the quantity supplied of a good is equal to the quantity demanded. When the market is not in equilibrium, market surplus or market shortage occurs. The region that is above the price equilibrium indicates market surplus and the region below the price equilibrium indicates market shortage. Video
