Solving a system of equations we will see that they sold 80 adult tickets.
<h3>how many adult tickets were sold?</h3>
To solve this, we need to solve a system of equations. To define said systems of equations, we first need to define the variables, we will use:
- x = adult tickets sold.
- y = student tickets sold.
They sold 20 more adult tickets than student tickets, then:
x = y + 20
And they collected a total of $880, then:
x*$8 + y*$4 = $880
The the system of equations is:
x = y + 20
x*$8 + y*$4 = $880
Isolating y on the first equation we get:
y = x - 20
Replacing that on the other equation we get:
x*$8 + (x - 20)*$4 = $880
Now let's solve that for x.
x*$12 - $80 = $880
x*$12 = $880 + $80 = $960
x = $960/$12 = 80
They sold 80 adult tickets.
