3) Suppose that Philip is the best contractor in town, and he makes $400,000 a year.
Suppose that Julia Roberts is the best and highest paid actress in Hollywood, and she

sold to only a few individuals in a year.
b.can only be provided to a limited number of customers in a year, but Julia's work is
sold to millions of
individuals in a year - i.e., to anyone who has the willingness and ability to pay for
admission to her movies.
c.can be provided to a unlimited number of customers in a year, and Julia's work is sold
to millions of
