Answer:
Step-by-step explanation:
The equations can be written as ...
y = 350 -x . . . . . . . . total number of people
4x +2y = 1100 . . . . . admission fees collected
Substituting for y, we have ...
4x +2(350 -x) = 1100
2x = 400 . . . . . . . . . . . . subtract 700, collect terms
x = 200
y = 350 -200 = 150
