Admission prices at a football game were $5 for adults and $ 2 for children.

satela [25.4K]

Answer:

404 adult tickets were sold, and 250 child tickets.

Step-by-step explanation:

This question can be solved by a system of equations.

I am going to say that

x is the number of adult tickets sold.

y is the number of child tickets sold.

654 tickets were sold.

This means that

$x + y = 654$

$y = 654 - x$

Admission prices at a football game were $5 for adults and $ 2 for children. The total value of the tickets sold was $2520.

This means that

$5x + 2y = 2520$

Since $y = 654 - x$

$5x + 2(654 - x) = 2520$

$5x + 1308 - 2x = 2520$

$3x = 1212$

$x = \frac{1212}{3}$

$x = 404$

$y = 654 - x = 654 - 404 = 250$

404 adult tickets were sold, and 250 child tickets.
