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

• 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

Christian had brochures printed for a new business venture. Christian originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of $134. After those ran out, Christian spent $120 on 2 boxes of black-and-white brochures and 3 boxes of color brochures. Which system represents this situation?

• 2x+3y=134

  4x+3y=120

• 3x+3y=134

  4x+2y=120

• 4x+3y=134

  2x+3y=120

• 3x+3y=120

  4x+2y=134
