Question

Terri is starting a babysitting service to make some extra money. She plans to charge a base fee of $10 plus $7 per hour. Write a function that could be used to represent her total charge for the babysitting service, y, as a function of the number of hours she babysits, x.

Answer 1

y=7x+10

Explanation:

Step one:

Base fee Charge= $10

Charges per hour= $7

Let the number of hours be x

and let the total charges be y

Step two:

the linear function for the total charges can be represented using the equation of a straight line, which is

y=mx+c

where y= tota charges

m= the charges per hour

x= is the number of hours worked

c= the base fee

Step three:

the equation is

y=7x+10
