A standard formal algebraic setup for solving the problem....
x = # of adult tickets
600-x = # of child tickets
The total cost of the tickets was $4400:
That equation is easily solved using basic algebra:
x=400 adult tickets; so 600-x=200 children tickets.
ANSWER: 200 child tickets
If formal algebra is not required, here is a quick solution method using logical reasoning and simple mental arithmetic.
600 adult tickets would have cost $4800; 600 child tickets would have cost $3600.
The actual total, $4400, is 2/3 of the way from $3600 to $4800; therefore, 2/3 of the tickets were adult tickets.
So 2/3 of 600 = 400 adult tickets, and 1/3 of 600 = 200 child tickets.
