So, the sum of these two is what?
Directrix (directrix):
Child revenue is 12x

This is algebra.
We use variables.
Algebra is the science of finding x.
12x + 15y = ?

$33,546
OpenStudy (anonymous):
$33,456
Directrix (directrix):
x + y = 2450
12x + 15y = 33456
Take it to the wolf for solution.
OpenStudy (anonymous):
ok
Directrix (directrix):
x represents children
y represents adults
so don't put the children number in the adult slot and vice versa
