Question

A technician charges an initial fee of $300 plus an hourly fee of $60. Mr. Jenks paid the technician $480. How many hours did the technician work?

Answer 1

This translates to the equation `f=$300+hxx$60=$480`

Explanation:

Where `f=`total amount and `h=`number of hours.

Subtract the inital fee `$300` from the total:

`hxx$60=$180->h=($180)/($60)=3` hours

Answer 2

Technician worked for `3` hours.

Explanation:

Assume that the technician worked for `x` hours.

As he charges initial fee of `$300` plus an hourly fee of `$60`, his charges for `x` hours would be

`300+60x`

As Mr. Jenks paid `$480`,

`300+60x=480`

or `60x=480-300=180`

or `x=180/60=3`

Hence technician worked for `3` hours
