If the class collected $880 from ticket sales, how many adult tickets were sold?

Question

Adult tickets to the fall play cost $8 and student tickets cost $4. The drama class sold 20 more adult tickets than student tickets to the fall play. If the class collected $880 from ticket sales, how many adult tickets were sold? The drama class sold _____ adult tickets.

Answer 1

Let x = the number of student tickets

x + 20 = the number of adult tickets

 

4x + 8(x + 20) = 880

4x + 8x + 160 = 880

12x + 160 = 880

12x = 720

x = 60

 

There were 60 student tickets and 60 + 20 = 80 adult tickets sold.
