Question

11. Tickets to a football game were $5 for

children and $7 for adults. The total money
collected was $3379 and 587 people
attended. How many children attended the
game?

Answer 1

The number of children that attended the game was 365

Explanation:

Let

x ----> the number of children that attended the game

y ---> the number of adults that attended the game

we know that

`x+y=587` ----> equation A

`5x+7y=3,379` ----> 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
