Colin needs to save at least $200 for homecoming. He works 2 jobs earning $9 per hour at Wawa and $25 per hour mowing lawns. He only has time to work 16 hours before homecoming. Which system of inequalities represents this scenario?

• x + y ≥ 25

  x + y ≤ 9

• 100x + 25 y ≤ 200

  2x + 9y ≤ 16

• x + y ≥ 200

  9x + 25y ≤ 16

• 9x + 25y ≥ 200

  x + y ≤ 16
