This is the answer to the amusement park problem! Below are two equations and I defined the variables that are in those two equations.
(c + d = 278)-4
1.5c + 4d = 792
-4c + -4d = -1112
You are going to wind up with an equation like this: -2.5c = -320
C = Children at Amusement park
A = Adults at Amusement park
C = 128
A = 150
