Homework Help: algebra

The number of students attending the fall play was 150 more than the number of adults attending. Students tickets cost $3, and adult tickets cost 45 . A total of $4730 was collected. How many students attended the play?
this is what i have, but i need help on the equation.
let x = students let y= adults
x=y+150
x=3x+5y+150
150*3=450, 4730-450=4280, 4280/2=2140
the # of students is 2140+150=2290
4730-150=4

Your second equation is completely wrong. The two equations should be

x = y + 150
3x + 5y = 4730

So, 3(y +150) + 5y = 4730
8y = 4280

Solve for y, then x.
