The management of the Carnival Cinema was worried about breaking even on their movie “Elvis Returns from Mars.” To break even, they had to take in $5000 on the matinee. They were selling adult tickets for $8.50 and children's tickets for $5.00. They knew they had sold a total of 685 tickets. How many of those tickets would have to have been adult tickets for them to meet their goal? Homework Help ✎
Create a system of equations and solve.
Where a = number of adult tickets sold and c = number of children's tickets sold:
8.5a + 5c = 5000
a + c = 685
They would need to sell at least 450 adult tickets.
