The system of equations would be:
64x+132y = 1040
x = 2y
We multiply the number of adult tickets, 64, by the cost of the adult tickets, x.┬а ┬аWe multiply the number of student tickets, 132, by the cost of the student tickets, y.┬а Together these add up to $1040.
We know that the cost of an adult ticket is twice as much as a student ticket, so x = 2y.
