Question

A group of 45 people attended a ball game. There were twice as many children as adults in the group. Set up a system of equations that represents the numbers of adults and children who attended the game and solve the system to find the number of children who were in the group

Answer 1

Let \(a\) be number of adults and \(c\) be number of children.
What equations do you get from:
"A group of 45 people"

"There were twice as many children as adults in the group"

Answer 2

a+c=45
c= 2a?

Answer 3

Yeah!

Answer 4

So then would it be 15 adults and 30 children?

Answer 5

Yeah.

Answer 6

Ok thanks!!!
