14-23 Variance analysis, multiple products. The Detroit Penguins play in the American Ice Hockey League. The Penguins play in the Downtown Arena (owned and managed by the City of Detroit), which has a capacity of 15,000 seats (5,000 lower-tier seats and 10,000 upper-tier seats). The Downtown Arena charges the Penguins a per-ticket charge for use of its facility. All tickets are sold by the Reservation Network, which charges the Penguins a reservation fee per ticket. The Penguins' budgeted contribution margin for each type of ticket in 2012 is computed as follows: Lower-Tier Tickets Upper-Tier Tickets Selling price $35 $14 Downtown Arena fee 10 Reservation Network fee 5 Contribution margin per ticket $20 $5 The budgeted and actual average attendance figures per game in the 2012 season are as follows: Budgeted Seats Sold Actual Seats Sold Lower tier 4,000 3,300 Upper tier 6,000 7,700 Total 10,000 11,000 There was no difference between the budgeted and actual contribution margin for lower-tier or uppertier seats.
