The admission fee for a charity event is $7 for children and $10 for adults. The event was attended by 700 people, and the total amount collected in admissions was $6,400.
There were ___children and ___ adults at the show.

Answer 1

there were 200 children and 500 adults

Explanation:

Answer 2

c = children, a = adults
c + a = 700...c = 700 - a
7c + 10a = 6400

7(700 - a) + 10a = 6400
4900 - 7a + 10a = 6400
3a = 6400 - 4900
3a = 1500
a = 1500/3
a = 500

a + c = 700
500 + c = 700
c = 700 - 500
c = 200

there were 200 children and 500 adults
