12. The price elasticity of demand for widgets is 0.80. Assuming no change in the demand
curve for widgets, a 16 percent increase in sales implies a:
13. Suppose Aiyanna's Pizzeria currently faces a linear demand curve and is charging a very
high price per pizza and doing very little business. Aiyanna now decides to lower pizza prices
by 5 percent per week for an indefinite period of time. We can expect that each successive
week:
14. The price elasticity of demand of a straight-line demand curve is:

15. A leftward shift in the supply curve of product X will increase equilibrium price to a
greater extent the:
16. If the demand for bacon is relatively elastic, a 10 percent decline in the price of bacon
will:
17. The price elasticity of demand is generally:

18. For a linear demand curve:
19. The price of product X is reduced from $100 to $90 and, as a result, the quantity
demanded increases from 50 to 60 units. Therefore demand for X in this price range:

20. The above diagram shows two product demand curves. On the basis of this diagram we
can say that:
21. Suppose we find that the price elasticity of demand for a product is 3.5 when its price is
increased by 2 percent. We can conclude that quantity demanded:
22. The price elasticity of demand for beef is about 0.60. Other things equal, this means that a
20 percent increase in the price of beef will cause the quantity of beef demanded to:

23. If a demand for a product is elastic, the value of the price elasticity coefficient is:
24. The concept of price elasticity of demand measures:

25. Refer to the above diagram. Between prices of $5.70 and $6.30:
26. Refer to the above diagram and assume a single good. If the price of the good decreases
from $6.30 to $5.70, consumer expenditure would:
27. Refer to the above diagram and assume a single good. If the price of the good increased
from $5.70 to $6.30 along D1, the price elasticity of demand along this portion of the demand
curve would be:

28. Suppose the price of local cable TV service increased from $16.20 to $19.80 and as a
result the number of cable subscribers decreased from 224,000 to 176,000. Along this portion
of the demand curve, price elasticity of demand is:
29. If the price of hand calculators falls from $10 to $9 and, as a result, the quantity demanded
increases from 100 to 125, then:
30. A perfectly inelastic demand curve:

31. If quantity demanded is completely unresponsive to price changes, demand is:
32. A firm can sell as much as it wants at a constant price. Demand is thus:
33. A demand curve which is parallel to the horizontal axis is:
