A good with a vertical demand curve has a demand with
A) infinite elasticity.
B) unit elasticity.
C) zero elasticity.
D) varying elasticity.
The demand curve in the figure above illustrates the demand for a product with

A straight-line demand curve with negative slope intersects the horizontal axis at 100 tons
perweek. At the midpoint on the demand curve (corresponding to 50 tons per week) the
priceelasticity of demand is

.
The figure above illustrates a linear demand curve. If the price rises from $6 to $8 demand
is________ and if the price falls from $8 to $6 demand is ________.

The demand curve in the figure above illustrates the demand for a product with
A) zero price elasticity of demand at all prices.
B) a price elasticity of demand that is different at all prices.
C) unit price elasticity of demand at all prices.
D) infinite price elasticity of demand.
A straight-line demand curve with negative slope intersects the horizontal axis at 200 tons
perweek. The point on the demand curve at which the price elasticity of demand is 1
corresponds to aquantity demanded
Demand is inelastic if Demand is unit elastic when Producers' total revenue will decrease if
A) the price rises and demand is inelastic.
B) income increases and the good is a normal good.

C) the price rises and demand is elastic.
D) income falls and the good is an inferior good.
