I'm having trouble with following practice exam problem:
36 persons are going on a trip. Adult ticket was 150$ more expensive than children's ticket. Total price of sold adult tickets was 4000$ and total price of sold children's tickets was 2000$. I'm supposed to calculate the total amount of children on the trip.
This is what I've done so far:
(Amount of adults) + (Amount of children)=36
or x + y =36
(Amount of adults)(base ticket price + 150)=4000
or x(z+150)=4000
and
(Amount of children)(base ticket price)=2000
or y(z)=2000
Then I get confused and get all kinds of nonsensical answers and/or can't get rid of any variables and it feels I'm running in circles. I'm starting to wonder if there's simpler way to approach the problem. The worst part: I've already deduced the correct answer like days ago, but still can't seem to make sensible formula for it. I know it can't be this hard. Any help is greatly appreciated.
