Question

Franco earns $8 per hour at his after-school job. Last week, he received a paycheck of more than $168. If he worked for h hours that week, find all the inequalities that represent this situation.

Answer 1

8h=168
168 divided by 8= h
h=21
He worked 21 hours

Answer 2

`8h>168`

`h>21`

Explanation:

Let h be the number of hours.

We have been given that Franco earns $8 per hour at his after-school job, so the amount earned after working h hours will be 8h.

Last week, he received a paycheck of more than $168. This means that the amount earned for h hours will be greater than 168.

We can represent this information in inequality as:

`8h>168`

Let us divide both sides of our inequality by 8.

`(8h)/(8)>(168)/(8)`

`h>21`

Therefore, Franco should have worked more than 21 hours.
