Lisa works two jobs to pay for college. She tutors for $18 per hour and also works in campus tech support for $10 per hour. Due to her class and study schedule, Lisa is only able to work up to 22 hours per week but must earn at least $210 per week. If T represents the number of hours Lisa tutors and C represents the number of hours she works in campus tech support, which system of inequalities represents this scenario?
a
T + C ≤ 22
10T + 18C ≤ 210
b
T + C ≥ 22
10T + 18C ≥ 210
c
T + C ≥ 22
18T + 10C ≤ 210
d
T + C ≤ 22
18T + 10C ≥ 210
