1. A major cereal manufacturer decides to lower prices from $3.60 to $3.00 per 15-ounce box. If quantity demanded increases by 18%, what is the price elasticity of demand? Is this an example of elastic or inelastic demand?
2. To increase state tax revenues, the Governor of California has proposed an additional sales tax on all automobiles deemed to be exotic in nature; that is, two door coupes and convertibles with a dealer sticker price of at least $100,000. Comment on the validity of this proposed tax.

a. An increase in demand, all things equal
b. A decrease in demand, all things equal
c. An increase in supply, all things equal
d. A decrease in supply, all things equal

1. Elasticity is defined as percentage change in quantity demanded/percentage change in price.
Quantity demanded increased by 18%
Price decreased by (3.6-3)/3 = 20%
Thus elasticity = - 18/20 = -0.9
Since mod(E) < 1 the demand is inelastic.
2. The purpose of sales tax is to increase state revenue. However, if an increase in tax, decreases the demand ...

Do you agree or disagree with each of the following statements? Briefly explain your answers.
(a) The price of a good rises, causing the demand for another good to fall. The two goods are therefore substitutes.
(b) If demand increases and supply increases at the same time, price will clearly rise.
(c) A shift in supply causes the price of a good to fall. The shift must have been an increase in supply.
