Answer:
The number of children is 2500 and the number of adults that attended the game is also 2500.
Step-by-step explanation:
Let us consider that, number of children be x and number of adults be y that attend game.
Since, total 5000 people attend the game.
It costs $3 for children and $7 for adults and the total takings at the door was $25000
      Â
Substitute value of x from equation 1 into equation 2.
    Â
So that,
Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.
Try this method to answer without algebra.
If everyone paid $3 the 5000 would pay 5000 x $3 = $15000
The extra $10000 must come from the extra $4 the adults pay
$10000 / $4 = 2500
So there must be 2500 adults and 2500 children
If everyone paid $3 the 5000 would pay 5000 x $3 = $15000
The extra $10000 must come from the extra $4 the adults pay
$10000 / $4 = 2500
So there must be 2500 adults and 2500 children
