Respuesta :
The number of children is 2500 and the number of adults that attended the game is also 2500.
System of equations:
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.
[tex]x+y=5000\\\\x=5000-y..........(1)[/tex]
It costs $3 for children and $7 for adults and the total takings at the door was $25000
[tex]3x+7y=25000 .............(2)[/tex]
Substitute value of x from equation 1 into equation 2.
[tex]3(5000-y)+7y=25000\\\\15000-3y+7y=25000\\\\4y=10000\\\\y=10000/4=2500[/tex]
So that, [tex]x=5000-2500=2500[/tex]
Thus, the number of children is 2500 and the number of adults that attended the game is also 2500.
