The student council determined that its profit from the upcoming prom is directly related to the ticket price or the dance. Looking at past dances, the council realized that the profit can be modeled by the function p(t) =-1212 +4801-30 where t represents the cost (in dollars) of each ticket. a.) What ticket price will maximize the profit that the student council earns from the prom? b.) What is the maximum profit that the student council will receive?
