Nick works two jobs to pay for college. He tutors for $15 per hour and also works as a bag boy for $8 per hour. Due to his class and study schedule, Nick is only able to work up to 20 hours per week but must earn at least $150 per week. If t represents the number of hours Nick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario?

If t is the number of hours tutoring and b is the number of hours as bag boy, then t + b <= 20 He needs at least $150/week: 15t + 8b >= 150 None of the systems shown represent this scenario.

No of hours he tutors = t
Amount earned = 15t
Hours as bag boy =b
Amount earned =8b
8b+15t must be>= $150
Amount earned = 15t
Hours as bag boy =b
Amount earned =8b
8b+15t must be>= $150
