unitary elastic. |

elastic. |

perfectly inelastic. |

inelastic. |

perfectly inelastic. |

9.

If the cross-price elasticity of demand between Good A and Good B is 2 and the percentage change in price of Good A is 5 percent, what is the percentage change in quantity demanded of Good B?

-3 percent |

1.50 percent |

10 percent |

3 percent |

-1.25 percent |

Answer #1

**8. Answer: Unitary elastic**

Price elasticity of demand = % change in quantity demanded / % change in price

Price elasticity of demand = 30% / 30% = 1

If Price elasticity of demand = 1, demand is unitary elastic.

**9. Answer: 10%**

Cross-price elasticity of demand = % change in quantity demanded for good B / % change in price of good A

2 = % change in quantity demanded for good B / 5%

2*5% = % change in quantity demanded for good B

10% = % change in quantity demanded for good B

When the price of good "X" increases 20 percent (+20%), Harry
decreases his quantity demanded of "X" by 25 percent while Meghan
decreases her quantity demanded of "X" by 15 percent. Harry's
demand for good "X" is (relatively inelastic / unitary elastic /
relatively elastic) and Meghan's demand for good "X" is (relatively
inelastic / unitary elastic / relatively elastic).
A. Relatively inelastic; relatively
inelastic.
B. Relatively inelastic; relatively
elastic.
C. Unitary elastic; relatively
elastic.
D. Relatively elastic; relatively
elastic.

A price change causes the quantity demanded for a good to
increase by 20 percent and the total revenue of that good decreases
by 15 percent. What can you say about the price elasticity of
demand at this point.
It's elastic
It's inelastic
It's unitary elastic
It's perfectly elastic

percentage change in price for good B, then the demand for good B
is
a.
inelastic.
b.

c.
elastic.
d.
perfectly elastic.
QUESTION 23
If the percentage change...

A price change causes the quantity demanded of a good to
increase by 2 percent, while the total revenue of that good
decreased by 8 percent. Over this price range is the demand for
this good elastic, inelastic or unitary elastic? Could anyone
explain, please?

A measure of the rate of percentage change of quantity demanded
with respect to price, holding all other determinants of demand
constant is
a.
Income elasticity of demand
b.
Own price elasticity of demand
c.
Price elasticity of market equilibrium
d.
Cross price elasticity of demand
The value of the income elasticity of demand coefficient for
Good X is given as 0.1. This means that
a.
as income increases by 10 percent, quantity demanded rises by 1
percent.
b.
as income...

When the price is $2, quantity demanded is 10. When the price
rises to $8, quantity demanded falls to 2.
What is the value of the elasticity of demand? Is it elastic or
inelastic?

In Market A, a 4 percent increase in price reduces the quantity

a) unit price-elastic; perfectly price-inelastic.
b) price-elastic; price-inelastic.
c) perfectly price-elastic; unit price-elastic.
d) price-inelastic; price-elastic.
