Please show me how to set this up and how to solve. Thanks in advance.
At the local ballpark, the team charges $5 for each ticket and expects to make $1,300 in the concessions. The team must pay its players $1800 and pay all other workers $1500. Each fan gets a free bat that cost the team $3 per bat. How many tickets must be sold to break even?
number of tickets sold --- n
profit = income - expenses
= 5n -( 3n+1300 + 1800)
= 2n - 3100
to "break even", the profit is zero, so ...
2n - 3100 = 0
2n = 3100
n = 1550
to break even they must sell 1550 tickets.
