Question

Rick works two jobs to pay for college. He tutors for $20 per hour and also works as a bag boy for $7 per hour. Due to his class and study schedule, Rick is only able to work up to 25 hours per week, but must earn at least $200 per week. If t represents the number of hours Rick tutors and b represents the number of hours he works as a bag boy, which system of inequalities represents this scenario?

Answer 1

he needs at least 200 per week:

20t+7b>=200

he can work up to 25 hours per week:

t+b<=25

this is your system of inequalities.
