Given :
The charges per ticket = $60
The stadium, labor, and other overhead costs will total $39,000
We need to find the number of tickets to earn a profit at least $50,000
So, let the number of tickets = x
So,
The total charges should equal the profit and the total cost of the stadium, labor, and other overhead
so,

the number of tickets is integer number
So,
The number of tickets should be 1,484
