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

c = -381.50/-3.50 = 91
The number of child tickets sold that day was 91.
