The members of the city cultural center have decided to put on a play once a night for a week. their auditorium holds 600 people. by selling tickets, the members would like to raise $3 comma 300 every night to cover all expenses. let d represent the number of adult tickets sold at $7.50. let s represent the number of student tickets sold at $4.50 each. if all 600 seats are filled for a performance, how many of each type of ticket must have been sold for the members to raise exactly $3 comma 300? at one performance there were three times as many student tickets sold as adult tickets. if there were 480 tickets sold at that performance, how much below the goal of $3 comma 300 did ticket sales fall?
