If you get printed tickets from the ticket office, the price will be on there. I did this for a couple games this year I gave to family members, because it was easier to hand them a ticket than deal with apps and cell phones.
Or, take your full price for the season and divide by 10. That'll be your price per game.
Start at a 10% flat income tax. Can be raised each year if needed, but only .5% a year, until it reaches 20%. It can be lowered by any amount though.
