Multistep Sandy charges each family that she babysits a flat fee of $10 for the night and an extra $5 per child.kimmi charges $25 per night no matter how many children a family has write a equation that compare the two girls also is the fees are the same how many children a family have to have in order to be the same
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
Step-by-step 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.
