Answer:
The number of children that attended the game was 365
Step-by-step explanation:
Let
x ----> the number of children that attended the game
y ---> the number of adults that attended the game
we know that
[tex]x+y=587[/tex] ----> equation A
[tex]5x+7y=3,379[/tex] ----> equation B
Solve the system by graphing
Remember that the solution of the system is the intersection point both graphs
The solution is the point (365,222)
see the attached figure
therefore
The number of children that attended the game was 365
