Assuming this, you have to start by writing two equations from the information provided: 180 total tickets were sold x+y=180 they made $590 and adult tickets cost $4 and kids tickets cost $2 180=4x+2y
lets solve for x in the first equation: x=180-y we can plug this into the second equation and solve for y 590=4(180-y)+2y 590=720-4y+2y 590=720-2y -130=-2y y=65
we can plug this into the first equation and solve for x: x+65=180 x=115
