Ms. Layne wants to build a rectangular deck in her back yard. She wants the length of the deck to be exactly 9 feet. She wants the perimeter of her deck to be, at most, 28 feet. The perimeter of any rectangle can be found by using the expression P=2(l+w), where l represents the length and p represents the width. Write an inequality that could be used to represent w, the possible widths, in feet, she could use for her deck.
28 >= 2(9 + w)
5 >= w
w <= 5
