If that allotment of tickets is correct, then the average price of tickets would be 121 dollars a ticket. An Arena show with those prices and numbers of tickets would produce a gross of $2,554,999.
For the average ticket price to be below $100 dollars for a North America Arena you would need a price distribution like this: 2,000 - $50 tickets, 17,000 - $90 tickets and 2,000 $225 tickets. That would be an average ticket price of $99.
In that situation, the floor and only the floor with be the $225 ticket range. All other tickets would be $90 dollars, except the 2nd level behind the stage which would be $50. This is actually probably how its going to be done.
