Question

An amusement part sells children

tickets, c, for $15 and adult tickets,
a, for $22. On Monday they sold
438 tickets and earned a total of
$7,067. How many children and
adult tickets did they sell on
Monday?

Answer 1

Let x = number of adult tickets
Then,x+147 = number of children's tickets

8/1 = (x+147) / x

x + 147 = 8x

7x = 147

x = 21

They sold 21 adult tickets and 168 children's tickets.
