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

Answer:
x = 2
Step-by-step explanation:
<u>Step 1: Set 3x - 2 equal to 5x - 6 to get x</u>
3x - 2 = 5x - 6
<u>Step 2: Solve for x</u>
3x - 2 + 6 - 3x = 5x - 6 + 6 - 3x
4 / 2 = 2x / 2
2 = x
Answer: x = 2
