Counting in your current expansion
Bleachers: You may as well leave them at 14, but I see you have bad schedule for the final 4 home games. Prior to those home matches you have top teams, 86ers, brackets team name, and CL1. Don't know if samar dark angels are beatable. Previous game losses tend to be a killer for bleacher sales, so you can lower the prices at 13 or 12.
Lower tiers: 1100*40=44000 dollars. Divided with 1600, equals 27.5. Guess you could try at about 33?
Courtside: Increase them some, maybe at 140? Do you remember what was your price in the first part of the season, when you sold about 160 in the first 4 games? We can use that for estimating.
Luxes: Try 600-700
