Question

Two families went to the movies. The Davis family paid $39 for 2 adult

tickets and 3 student tickets. At the same theater, the Tyler family paid $23
for 1 adult ticket and 2 student tickets. What is the price of a student
ticket?

Answer 1

$7

Explanation:

Let a be the price of the adult ticket and s be the price of the student ticket

That means that:

2a+3s=39

and

a+2s=23

Using elimination

-2(a+2s=23)

-2a-4s=-46

-2a-4s=-46

2a+3s=39

Eliminate a:

-s = -7 ; s = 7

I probably made this so much more complicated than it should be but...
