Booth Area Inequality - College Algebra

  • 0:00 - 0:04
    Since we know that our area needs to be less than or equal to 750 square feet.
  • 0:04 - 0:09
    We can just replace area on the left side of this inequality with the other way
  • 0:09 - 0:13
    we know how to express it, length times width. And then, plugin those side
  • 0:13 - 0:18
    lengths using these quantities down here. So the new length, of Grant's booth,
  • 0:18 - 0:23
    will be 20 feet, the original 20 feet, plus x, the amount that he's adding on.
  • 0:23 - 0:28
    So we have 20 plus x and then that's multiplying it by the new width, which will
  • 0:28 - 0:33
    be 15 plus x. This quantity will be the new area, which we know must be less
  • 0:33 - 0:36
    than or equal to 750. So here's our inequality.
