A semiprofessional baseball team near your town plays two home games each month at the local baseball park. They split the concessions 50/50 with the city, but keep revenue from ticket sales for themselves. The city charges the team $100 each month for the three-month season. The team pays the players and manager a total of $1,000 a month. The team charges $10 for each ticket, and the average customer spends $7 at the concession stand. Attendance averages 30 people at each home game. In order to break even, how many tickets does the team need to sell for each game?
