Question

Paul earns $5 per hour working after school. He needs at least $210 for a stereo system. Write and solve an inequality that describes the number of hours h he must work to reach his goal. 5h ≤ 210; at least 42 hours 210h ≥ 5; more than 42 hours 5h ≥ 210; at least 42 hours 5h > 210; more than 42 hours

Answer 1

5x =210
x is equal to 42

Answer 2

5h
`\geq` 210; at least 42 hours.

Basically, it's because he has to make 210 or more to afford the stereo, and since he earns $5 per hour, then that has to be greater than 210.
