Answer:

143.75/6.25=23 hours

Answer:

6.25h ≥ 143.75; h ≥ 23; 23 hours

Step-by-step explanation:

Levi earns $6.25 per hour after school. Since he needs at least $143.75 to get a stereo the amount he wants should be equal to or greater than  $143.75.

Let

h = number of hours worked

The expression can be written as follows:

6.25 × h ≥  143.75

6.25 h ≥  143.75

divide both sides by 6.25

h ≥ 143.75/6.25

h ≥ 23 hours
