Inequality Word Problems Review

Sean earns $6.70 per hour working after school. He needs at least $155 (≥ 155) for a stereo system. Write an inequality that describes how many hours he must work to reach his goal. $6.70 h ≥ 155 Per means to multiply To figure your pay check: You multiply rate times hours worked So 23 hours is not enough So Sean must Work 24 hours To earn enough Money.

Sean earns $6.85 per hour working after school. He needs at least $310 (≥ 310) for a stereo system. Write an inequality that describes how many hours he must work to reach his goal. $6.85 h ≥ 310 Per means to multiply To figure your pay check: You multiply rate times hours worked So 45 hours is not enough So Sean must Work 46 hours To earn enough Money.
