Answer 1

We know that

• She charges $5 for gas plus her hourly rate of $8 per hour.

,

• The given function is f(x)=5+8x.

To find the total amount she will charge, we use the given function. SO, for a 5 hours job, Sierra earns

`f(5)=5+8(5)=5+40=45`

She would earn $45 for 5 hours of babysitting.
