Question

An electrician charges a fee of $25 plus $20 per hour to repair wiring. Write an equation. To represent the electricians fee in functional notation using F for the fee and h for the number of hours worked. F(h)=_______

Answer 1

Using F for the fee and h for the number of hours worked, we have to consider that there is one quantity that depends on the number of hours ($20), and one that is fixed ($25).

Considering the latter, we can write the following equation:

`F(h)=20h+25`

Answer:

`F(h)=20h+25`
