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
