 C. Elastic demand to see movies in the afternoon    
D. Inelastic demand to see movies in the afternoon  
 
3. Airlines charge business travelers more than leisure travelers because there is a more: 
 
A. Elastic supply of business travel  
B. Inelastic supply of business travel

4. For which product is the income elasticity of demand most likely to be negative? 
 
A. Computer software  
 B. Used clothing    
C. Basketballs  
D. Bread  
 
5. Most goods can be classified as normal goods rather than inferior goods. The definition of a normal good suggests that: 
 
A. The income elasticity of demand for the good is negative  
B. The price elasticity of demand for the good is negative  
 C. The income elasticity for the good is greater than 0    
D. The cross elasticity of demand for the good is positive  
 
6. The cross elasticity of demand for product X with respect to the price of product Y is -1.2. It can be inferred that X and Y are: 
 
A. Substitute products  
 B. Complementary products    
C. Luxury products  
D. Unrelated products  
 
7. If a 10 percent increase in the price of one good results in no change in the quantity demanded of another good, then it can be concluded that the two goods are: 
 
A. Complementary goods  
B. Substitute goods  
 C. Independent goods    
D. Normal goods  
 
8. The price elasticity of demand for a textbook is estimated to be 1 no matter what the price or quantity demanded. In this case: 
 
A. A 10 percent increase in price will result in a 10 percent increase in total revenues  
 B. A 10 percent increase in price will result in a 10 percent decrease in the quantity demanded    
C. A 10 percent increase in price will result in a 10 percent decrease in total revenues  
D. A 10 percent increase in price will result in a 10 percent increase in quantity demanded  
 
9. If demand for farm crops is inelastic, a good harvest will cause farm revenues to: 
 
A. Increase because of the increase in the quantity that farmers can sell  
B. Increase because of a downward movement along the supply curve, encouraging an increase in demand  
 C. Decrease because of a percentage fall in price greater than the percentage increase in quantity sold    
D. Remain unchanged, because the increase in quantity that can be sold will be matched by an equal decrease in price  
 
10. You are the newly appointed sales manager of the Rock Record Company and have been charged with the task of increasing revenues. Your economics consultants have informed you that at present price and output levels, price elasticity of demand for your product is less than one. You should:

 C. Inelastic    
D. Perfectly elastic
