san4es73 [151]

Answer:

Student tickets cost $8 and adult tickets cost $5.

Step-by-step explanation:

12a + 12y = 156

6a + 11y = 118

We can multiply the second equation by -2 to try and cancel out the a variable.

$12a + 12y = 156\\-12a - 22y = -236\\\\-10y = -80\\y = 8$

Now that we know that the student tickets cost $8, we can substitute it into an equation to find the value of a, the adult tickets.

$12a + 12\cdot8 = 156\\12a+96=156\\12a=60\\a=5$

So, adult tickets cost $5 and student tickets cost $8.

Hope this helped!
