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? (1 point)

t + b less than or equal to 25
20t + 7b greater than or equal to 200

t + b greater than or equal to 25
20t + 7b = 200

t + b less than or equal to 25
20t + 7b less than or equal to 200

None of the systems shown represent this scenario.
