I am not going to answer each but here is a general answer.
y is total price and x is number of kids
Sandy's equation would be y= 10+5x
Kimmi's equation would be y= 25

For them to equal we would have 25=10+5x
Simplify 
5x=15
x=3
So for them to be equal, Sandy should have 3 kids.

So if someone has 5 children then he should choose Kimmi
