Answer:

  • 150 children
  • 200 adults

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

150 children and 200 adults attended the fair.
