Problema Solution
The school sells tickets for $11 main floor and $7 balcony. If they sell twice as many main floor tickets as balcony tickets and made $870, how many of each ticket did they sell?
Answer provided by our tutors
let 'x' represent the number of balcony tickets sold, then '2x' represents the number of main floor tickets sold
870 = 7x + 11(2x)
solving for 'x' we have x=30
2*30 = 60
30 balcony and 60 main floor tickets sold
