Question

A total of 635 tickets were sold for the school play. They were either adult tickets or student tickets. There were 65 fewer student tickets sold than adult tickets. How many adult tickets were sold?

Answer 1

You can make an equation for this (x is the number of student tickets)
$x + (x + 65) = 635 \\ 2 x + 65 = 635 \\ 2x = 635 - 65 \\ 2x = 570$
$x = \frac{570}{2} = 285$
the number of student tickets is 285

the number of adult tickets is 285+65=350



good luck
