First, I just thought of a random number divisible by 10. For practical purposes, lets say I chose 20.

I multiplied 20 by 3 since there were three times as many adult tickets sold than there were children tickets. This gives me 60 tickets sold in total for adults.
$9.40 * 60 = 564

Then I divided this number by 3 to get the number of children tickets sold. This gives me 20 tickets sold in total for children.
$5.10 * 20 = 102

I then added both numbers.
$564 + $102 = $666
