@satellite73 Before you do this, please come help me really quick
OpenStudy (anonymous):
i guess you are supposed to solve \[3x+5y=2815\\x+y=723\]
OpenStudy (anonymous):
in the second equation you can put \(y=723-x\) and substitute in to the first equation to get \[3x+5(723-x)=2815\] and solve that one
OpenStudy (anonymous):
Thank you, so x will be the number of students and 723-x is th non-student tickets right?
