Football Question

$35 tickets - 14000
$20 tickets - 22500

I found this by making an equation and setting it equal to the total revenue.After that I solved for x.
$940,000=35(number of $35 tickets) + 20(number of $20 tickets)
(x)-being the total number of 35 dollar tickets
(36500-x) being the total number of 20 dollar tickets
