(C)  The Gigamultiplex Movie Palace's current standard adult ticket price is \$12.  The
theater is currently selling 2500 tickets on a typical day.  By surveying their customers, the
management projects that each $\$0.25$ increase in the adult ticket price will reduce
the number of tickets sold by 20.  
\bigskip
\item{1)}  Is this a situation for a linear model or an exponential model?  Why?
\item{2)}  Let $P$ be the price of a standard adult ticket.  Give a formula for the 
number of tickets sold as a function of $P$ according to the management's projection.
\item{3)}  How would find the total ticket sales revenue generated as a function of 
the price?  What price will yield the largest ticket sales revenue?
