Word problem please help​

A

Step-by-step explanation:

s = cost of senior ticket

c = cost of child ticket

System of Equations:

8s + 7c = 211

4s + 6c = 138

I used the elimination method and multiplied the second equation by -2

-8s - 12c = -276

add the above to the first equation and get

-5c = -65

c = 13

now find s

8s + 7(13) = 211

8s + 91 = 211

8s = 120

s = 15

7/8

Step-by-step explanation:

If you used the quadratic formula, you would get 7/8 as your solution. Hope this helps!!
