You will need 1100 tickets.
Step-by-step explanation
We firstly need to add up the total amount of fees, which is $2000 + $1600 = $3600. We then minus the $1400 in concessions, giving us $2200.
When this is divided by 5, we get 440 tickets. However, because each ticket comes with a $3 bat, we know we need to earn an extra $1320. To do this, we need to divide this by $2. This is because all of these tickets still come with a $3 bat.
This gives us another 660 tickets. When these are added together you will need 1110 tickets to break even.
Hope this helps!
