Price elasticity of demand measures
how responsive quantity demanded is to a change in price.
Suppose the value of the price elasticity of demand is -3. What does this mean?
A 1 percent increase in the price of the good causes the quantity demanded to decrease by 3 percent.
If the percentage increase in price is 15 percent and the value of the price elasticity of demand is -3, then quantity demanded
will decrease by 45 percent.
A demand curve that is ________ represents perfectly inelastic demand, and a demand curve that is ________ represents inelastic demand.
vertical; downward sloping
Seth is a competitive body builder. He says he has to have his 12-oz package of protein powder to “feed his muscles” every day. On the basis of this information, what can you conclude about his price elasticity of demand for protein powder?
It is perfectly inelastic.
If 50 units are sold at a price of $20 and 80 units are sold at a price of $15, what is the absolute value of the price elasticity of demand? Use the midpoint formula.

Suppose a hurricane decreased the supply of oranges so that the price of oranges rose from $120 a ton to $180 a ton and quantity sold decreased from 800 tons to 240 tons. What is the absolute value of the price elasticity of demand? Use the midpoint formula.

Which of the following statements about elasticity of demand is false?
The value of the price elasticity of demand is the reciprocal of the value of the demand curve’s slope.
The demand for all carbonated beverages is likely to be ________ the demand for Dr. Pepper.
less elastic than
Which of the following would result in a higher absolute value of the price elasticity of demand for a product?
A wide variety of substitutes are available for the good.
If the market for a product is broadly defined, then
there are few substitutes for the product and the demand for the product is relatively inelastic.
If the market for a product is broadly defined, then
there are few substitutes for the product and the demand for the product is relatively inelastic.
Which of the following could explain why the demand for table salt is inelastic?
Households devote a very small portion of their income to salt purchases.
Suppose a convenience store owner in Philadelphia was worried that the implementation of the 1.5 cents per ounce tax on sweetened beverages would cause the quantity demanded to fall by so much that he would be in a worse situation if he passed the tax on to customers by raising prices than if he did not raise prices. If raising the price of sweetened beverages would cause the owner to receive less total revenue from the sale of sweetened beverages, the demand for sweetened beverages is
