Pdcms sold a total of 110 tickets for the school play. an adult ticket is $7 and a student ticket is$4. the school collected a total of $569 how many adults and how many students attended the play

Let the number of adult tickets be x.
Since there are 110 tickets sold in all, student tickets will be 110 - x.

Cost for adult tickets = 7*x = 7x
Cost for student tickets = 4*(110 -x) = 4*110 - 4*x = 440 - 4x

Total cost = $569

7x + (440 - 4x) = 569

7x + 440 - 4x = 569

7x - 4x = 569 - 440

3x =   129

x = 129/3

x = 43

Recall x is the number of adults tickets = 43

Student tickets = (110 - x) = 110 - 43 =  67

Therefore from the number of tickets sold it is safe to assume that 43 adults and 67 students attended the play.
