Ows Challenge The members of the city cultural center have decided to put on a
play once a night for a week. Their auditorium holds 500 people. By selling
tickets, the members would like to raise $2,850 every night to cover all
expenses. Let d represent the number of adult tickets sold at $7.50. Lets
represent the number of student tickets sold at $4.50 each. If all 500 seats are
filled for a performance, how many of each type of ticket must have been sold
for the members to raise exactly $2,850? At one performance there were three
times as many student tickets sold as adult tickets. If there were 480 tickets sales sold at that performance, how much below the goal of 2,850 did ticket sales fail
