D

A major state university in the South recently raised tuition by 12%. An economics professor at this university asked his students, "How many of you will transfer to another university because of the increase in tuition?" One student in about 300 said that he or she would transfer. Based on this information, the price elasticity of demand for education at this university is: A 1. B highly elastic. C 0. D highly inelastic.

B

A men's tie store sold an average of 30 ties per day at $5 per tie but sold 50 of the same ties per day at $3 per tie. The price elasticity of demand, by the midpoint method, is: A greater than zero but less than 1. B equal to 1. C greater than 1 but less than 3. D greater than 3

C

Gas prices recently increased by 25%. In response, purchases of gasoline decreased by 5%. According to this finding, the price elasticity of demand for gas is: A 2. B 0.5. C 0.2. D 5.

B

Since the price of walnuts increases as the demand for cashews increases, we can assume that these two goods are: A unrelated. B substitutes. C superior. D inferior.

C

Suppose that an increase in the price of a good leads to an increase in total revenue. Ignoring other factors (like supply), at its current price the good must be: A price-elastic. B perfectly price-elastic. C price-inelastic. D inferior.

D

Suppose the price of university sweatshirts increases from $10 to $20 and the quantity supplied increases from 20 to 30. The price elasticity of supply, using the midpoint formula, is: A 1.66. B 1.50. C 0.66. D 0.60.

D

The income elasticity of demand for eggs has been estimated to be 0.57. If income grows by 5% in a period, all other things unchanged, demand will: A decrease by more than 5.7%. B decrease by less than 5.7%. C increase by more than 5.7%. D increase by about 2.9%.

A

The price elasticity of demand along a demand curve with a constant slope: A decreases in absolute value as quantity demanded rises. B is greater than the slope. C is less than the slope. D is equal to the slope.

A

The price elasticity of demand can be found by: A comparing the percentage change in quantity demanded to the percentage change in price. B knowing that when price changes, quantity demanded goes in the opposite direction. C examining only the slope of the demand curve. D measuring absolute changes in price and quantity demanded

D

The price elasticity of demand for fresh tomatoes has been estimated to be 2.22. If a new insecticide and fertilizer treatment yields a 20% increase in the nation's fresh tomato crop, how will that affect total revenue from fresh tomatoes, all other things unchanged? A Total revenue will fall. B The information is insufficient to answer the question. C Total revenue will remain unchanged. D Total revenue will rise.

B
