Answers

  1. The inequality which represents the range of actual weights w (in ounces) of the tub of toothpaste is :
    option d) 3.25 ≤ w ≤ 3.75
    Given:
    the indicated weight on a tube of toothpaste is 3.5 ounces.
    the actual weight varies by up to 0.25 ounce.
    Thus the lowest weight might be:
    3.5 – 0.25 = 3.25 ounces
    The highest weight might be:
    3.5 + 0.25 = 3.75 ounces
    Thus the range is:
    3.25 ≤ w ≤ 3.75
    Hence we get the required range.
