He can work no more than 20 hours a week, but he wants to earn at least $220 per week. Which of the following systems of inequalities represents this situation, where x is the number of hours worked as a tutor, and y is the number of hours worked as a lifeguard? * A 12x + 9.5y ≤ 220 AND x + y ≥ 20
B 12x + 9.5y ≤ 220 AND x + y ≤ 20
C 12x + 9.5y ≥ 220 AND x + y ≤ 20
D 12x + 9.5y ≥ 220 AND x + y ≥ 20
