Question

A total of 600 tickets were sold for the school play. they were either adult tickets or student tickets. the number of student tickets sold was three times the number of adult tickets sold. how many adult tickets were sold?

Answer 1

Let the number of adult tickets sold be x.
Adult tickets = x
Chid tickets = 3x

A total of 600 were sold.
⇒ x + 3x = 600

Solve x:
x + 3x = 600
4x = 600
x = 600 ÷ 4
x = 150

Answer: 150 adult tickets were sold.
