Let x be the number of adults attending the carnival.
Thus, the number of children attending the carnival is 500 - x.
The total admission charges from adults is 10x and the total admission charges from children is 5(500 - x).
The total admission charges will be 10x + 5(500 - x) = $3,500.
Expanding the equation, we get 10x + 2500 - 5x = $3,500.
Combining like terms, we get 5x + 2500 = $3,500.
Subtracting 2500 from both sides, we get 5x = $1,000.
Dividing both sides by 5, we get x = 200.
Therefore, there should be 200 adults and 500 - 200 = 300 children attending the carnival. Answer: \boxed{200; 300}.
