Answer 1

n= night c= child
sandy= $10+$5c
kimmi= $25n
if sandy babysits 3 children for one night they will both be the same price
sandy= $10+5(3)=$25
kimmi= $25

Answer 2

Explanation:

Consider the provided information.

Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child.

Let x is the number of child, Sandy charges fixed fee of $10 and $5 for each child. Thus, the charges for one night is:

`10+5x`

Kimmi charges $25 per night no matter how many children a family has. Thus, the charges for one night is:

`25`

Now we need to write an equation that would compare the two girls charges:

`10+5x=25`

Thus, the required equation is
`10+5x=25`.

Now we need to find how many children a family have in order to be the same charges.

For the same charges solve the equation as shown:

`10+5x=25`

`5x=15`

`x=3`

So, the number of children has to be 3 for same charge.
