The first band costs $250 + 50% of ticket sales
The difference in the 1st and 2nd band is $300 which is compensated by the 50% of the sales clause.
Which means the organisers must sell enough tickets to equal the cost.
If 505 = 300 Then 100% = (100x300)/50 = 600
If 300 tickets cost $600 then each ticket must cost 600/300 = $2
