Charlene is knitting a baby blanket. She wants its width, w, to be at least half its length, l. She estimates that she has enoug
h yarn to put fringe around the blanket, as long as the perimeter of the blanket is no more than 180 inches. The system of inequalities shown represents the width of the blanket in inches, w, and the length in inches, l. w ≥ 0.5l
2l + 2w ≤ 180
What is the maximum length possible for her blanket?
I believe the answer is C - 60 inches. 60 x 2 = 120, which is both lengths, and since he width is half the length, then 30 x 2 = 60. So 130 (length) + 60 (width) = 180. So 60 inches would be the maximum length for both sides.
