At the local ballpark, the team is expecting to bring in $5 for each ticket it sells that day and expects to make a total of $1,400 in concessions. The team must pay its players $2,000 for the day and pay all other workers $1,600 for the day. Each fan that shows up to the game will also get a free bat that costs the team $3 per bat. What is the system of equations to solve this problem? How many tickets must be sold to break even?
