Question

An electrician charges a flat service fee to accept a job and an additional hourly rate to complete the job. The amount an electrician charges per job can be represented by the function E(x) = 125 + 24x, where x represents the number of hours she works on the job and 125 represents her flat service fee. What is the interpretation of the slope in the context of the problem?

If the electrician works for 24 hours, her pay will be $125.
If the electrician works for 0 hours, her pay will be $24.
For every hour the electrician works, her pay will increase $125.
For every hour the electrician works, her pay will increase $24.

Answer 1

Step-by-step explanation:

the 4th answer : for every hour the electrician works, her pay will increase $24.

the first option (when working for 24 hours she would get $125) would look like something like that :

125 = 5x + 9, x = 24

the second option (working 0 hours earning $24) would look like something like this :

C(t) = 24 + 24t

I

the third option (for every hour with she will get additional $125) would look like

C(t) = 125 + 125t
