Suppose the demand function for a good is expressed

Suppose the demand function for a good is expressed as Q = 100 - 4p. If the good currently sells for $10,
then the price elasticity of demand equals
A) -1.5.
B) -0.67.
C) -4.
D) -2.5. -0.67.
If an increase in income results in a rightward parallel shift of the demand curve, then at any given price,
the price elasticity of demand will have
If the demand function for orange juice is expressed as Q = 2000 - 500p, where Q is quantity in gallons
and p is price per gallon measured in dollars, then the demand for orange juice has a unitary elasticity
when price equals
If the demand curve for orange juice is expressed as Q = 2000 - 500p, where Q is measured in gallons
and p is measured in dollars, then at the price of $3, elasticity equals

If the demand for orange juice is expressed as Q = 2000 - 500p, where Q is measured in gallons and p is
measured in dollars, then at the price of $3, the demand curve
A) is elastic.
B) has a unitary elasticity.
C) is inelastic.
D) is perfectly inelastic. is elastic.
If the demand curve for comic books is expressed as Q = 10,000/p, then demand has a unitary elasticity
If the price elasticity of demand for a good is greater than one in absolute value, economists characterize
that demand is
If the price elasticity of demand for a good is less than one in absolute value, economists would
characterize consumers of this good
If the price of orange juice rises 10%, and as a result the quantity demanded falls by 8%, the price
elasticity of demand for orange juice is
A) -1.25.
B) inelastic.
C) Both A and B above.
D) Neither A nor B above. inelastic.
