Answer:
2 children 9 adults.
Step-by-step explanation::
$22 for adults and $15 for children.
Let x and y represent the unknown values and A represents cost for adults and C represents cost for children
C(x) + A(y)=228 would be one equation for this to figure out the amount of children to adults.
Since there are 11 people we know the x and y values when added cannot equal more than 11.
15(1) + 22(10)=235 So that's not correct
15(2) + 22(9) = 228 so that's the correct answer.
You could also graph if you weren't figuring out children to adults:
y=mx+b. y-intercept would be 11 because that's the amount of people altogether. y=__x+11. y=-1x+11. because of rise over run (1/-1= -1). So, it would also be a linear decreasing function!
