Question

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?

t + b 20
15t + 8b = 150

t + b 20
15t + 8b 150

t + b 20
15t + 8b 150

None of the systems shown represent this scenario.

Answer 1

Your inequalities aren't showing up in your post. But it should be:
\[t+b \le20\]
\[15t+20b \ge150\]

Answer 2

Sorry, I meant 8b.

Answer 3

15t+8b
