Each year, the student council at Briarwood High School sponsors a community talent show
to raise money. In previous years, the council
has discovered that profit from ticket sales,
P(x), is a function of the amount charged per
ticket, x, in dollars, as modeled by the equation
P(x) = 120x – 12x2. What amount should the
council charge for a ticket to make the greatest
profit? [The use of the accompanying grid is
