If the demand for one good decreases when the price of another good decreases, the two goods are ________ goods.
D) substitute

Suppose that the percentage change in demand is 10%, the price elasticity of supply is 2, and the percentage change in the equilibrium price is 3.33%. What is the price elasticity of demand?
B) 1

The price elasticity of demand for a good is relatively elastic if:
D) all of the above

If the demand for new cars is elastic, an increase in price will result in:
C) a decrease in total revenue.

Figure 3.2 illustrates the supply and demand for t-shirts. If the actual price of t-shirts is $10, we would expect that
Figure 3.2
D) there will be no change since the market is in equilibrium.

The quantity of pencils sold is 1000 at the unit price $0.5. Suppose the price elasticity of demand for pencils by the initial value method is 2, and you would like to increase the quantity sold to 1200. Then the new price for pencils must be:
D) $0.45.

A firm facing a linear demand curve maximizes its total revenue where demand is
D) unitary elastic.

The government sometimes creates an excess demand for a product by setting a maximum price at which the product may be sold to consumers. This is sometimes called a
A) price ceiling.

Suppose that David buys the same number of energy drinks every weekend no matter what happens to the price of the energy drinks. What does this suggest about David's demand for energy drinks?
B) It is perfectly inelastic.

In Figure 4.1 the demand curve that is perfectly inelastic is on graph:
Figure 4.1
A) A.

Figure 3.2 illustrates the supply and demand for t-shirts. If the actual price of t-shirts is $7, there is an
Figure 3.2
A) excess demand of 8 t-shirts.

When the price of pens went from $1 to $1.50, the quantity demanded of pencils changed from 50 to 75 a day. The cross-price elasticity of demand for pencils (using the initial value formula) is:
A) 1. ج

Suppose that the income elasticity of demand for new clothes is positive. Other things being equal, which of the following statements is correct?
D) all of the above

Figure 3.3 illustrates the demand for tacos. Assume that tacos and beer are complements. An increase in the price of beer would bring about a movement from
Figure 3.3
C) D2 to D1.

Suppose that the percentage change in demand is 20%, the price elasticity of demand is 3, and the price elasticity of supply is 2. What is the percentage change in the equilibrium price?
A) 4%

When demand decreases and the demand curve shifts to the left, equilibrium price ________ and equilibrium quantity ________.
D) decreases; decreases

Figure 3.5 illustrates a set of supply and demand curves for hamburgers. An increase in supply and an increase in quantity demanded are represented by a movement from
Figure 3.5
A) point a to point b.

If an increase in the price of good X results in a decrease in the quantity of Y demanded,
B) good X and good Y are complements.

Which of the following characteristics are of a linear demand curve?
A) It has a constant slope.

If consumers have a long time to respond to an increase in electricity prices their demand is likely to be ________ than if they are only given a short time.
C) more elastic

When the price of pens went from $1 to $1.50, the quantity demanded of pencils changed from 50 to 75 a day. The cross-price elasticity of demand for pens (using the initial value formula) is:
D) Cannot be determined from the information provided.


The demand for a particular good depends on variables such as:
D) all of the above

Figure 3.5 illustrates a set of supply and demand curves for hamburgers. A decrease in supply and an increase in demand are represented by a movement from
Figure 3.5
D) point c to point a.

If the price elasticity of demand is 0.5, this means that a ________ increase in price causes a ________ decrease in quantity demanded.
B) 30%; 15%

Figure 3.2 illustrates the supply and demand for t-shirts. If the actual price of t-shirts is $7, we would expect thatFigure 3.2
C) price will increase until quantity demanded equals quantity supplied.

Refer to Figure 3.6, which shows David's and Celeste's individual supply curves for flower arrangements per week. Assuming David and Celeste are the only producers in the market, if the market quantity supplied is 50, the price must be
Figure 3.6
C) between $10 and $20.

A good is said to be "inferior" if:
C) it has a negative income elasticity of demand.

If the demand curve facing a firm had a price elasticity of demand equal to zero and the firm raised its price, its total revenue would:
D) increase.

Figure 3.3 illustrates the demand for tacos. An increase in price of tacos would bring about a movement from
Figure 3.3
B) point c to point a.

Under which of the following conditions will an increase in demand cause a relatively small increase in price?
D) all of the above

If the price elasticity of demand is equal to zero and the price were to rise, the quantity demanded would:
C) not change.

As we move upward along a linear demand curve, the price elasticity of the demand
A) increases.

Figure 3.3 illustrates the demand for tacos. Assume tacos are a normal good. An increase in income would bring about a movement from Figure 3.3
D) D0 to D1.

Refer to Figure 3.6, which shows David's and Celeste's individual supply curves for flower arrangements per week. Assuming David and Celeste are the only producers in the market, what is the market quantity supplied at a price of $20?
Figure 3.6

Figure 3.6
B) 100

Figure 3.5 illustrates a set of supply and demand curves for hamburgers. A decrease in demand and a decrease in quantity supplied are represented by a movement from
Figure 3.5
C) point b to point c.

Refer to Table 4.3. After calculating the price elasticity of demand for computers, we can say the demand for computers is:
Table 4.3
D) elastic.

Which of the following statements is correct with respect to price elasticity of supply?
D) All of the above are correct.

The supply curve for gasoline will be more elastic in:
