Answer:
Step-by-step explanation:
Let x represent the number of hours that he works. babysitting his neighbors children.
Let y represent the number of hours that he works at the other job.
He earns $10 per hour babysitting his neighbors children. This means that the amount that he earns, babysitting his neighbors children for x hours would be
10x
He earns $12 per hour working at the other job. This means that the amount that he earns, working at the other job for y hours would be
12y
Therefore, the inequality that represent the number of hours that he needs to work at both jobs to earn a minimum of $120 is
10x + 12y ≥ 120
