Justin charges $11 to mow a small lawn and $26 to mow a large lawn. He would like to make at least $130.

Write an inequality that describes the situation.

Let x = # of small lawns mowed and

Let y = # of large lawns mowed

• 11x + 26y ≥ 130

• 11x + 26y ≤ 130

• 11x + 26y > 130

• 11x + 26y < 130

Charchit had brochures printed for a new business venture. He originally ordered 4 boxes of black-and-white brochures and 3 boxes of color brochures, which cost a total of Rs13400. After those ran out, Charchit spent Rs12000 on 3 boxes of black-and-white brochures and 3 boxes of color brochures. Which system represents this situation?

• x+y=13400

  x+y=12000

• 3x+3y=13400

  4x+3y=12000

• 4x+3y=13400

  3x+3y=12000

• 7xy=13400

  6xy=12000

• 4x + 6y = 3
  13.5x - 13y = 6
• x + y = 4
  x - y = 6
• 4x + 6y = 13
  3x + 7y = 13.5
• 4x - 6y = 13
  3x - 7y = 13.5
