Question

A total of 504 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

126

let a be the number of adult tickets sold

then the number of student tickets sold is 3a

thus a + 3a = 504

4a = 504

divide both sides by 4

a =
`(504)/(4)` = 126

there were 126 adult tickets sold
