Suppose that Juan Carlos is filling out a survey that he received in the mail. The survey asks him
what he would do
if the price of his favorite toothpaste increased. Juan Carlos reports that he
would switch to a different brand. The
survey asks what he would do if the price of all
toothpastes increased. Juan Carlos reports that he must use
toothpaste, so he would have to adjust
his spending elsewhere. These examples illustrate the importance of
a.

b.
a necessity versus a luxury in determining the price elasticity of demand.
c.
the definition of a market in determining the price elasticity of demand.
d.
