Answer:

  91 child tickets were sold

Step-by-step explanation:

Let c represent the number of child tickets sold. Then the number of adult tickets sold is (150-c) and the total revenue is ...

  5.20c +8.70(150-c) = 986.50

  -3.50c +1305 = 986.50 . . . . simplify

  -3.50c = -318.50 . . . . . subtract 1305

  c = -381.50/-3.50 = 91

The number of child tickets sold that day was 91.
