Question

Which inequality models this problem?
 
The length of a rectangle is four times its width. If the perimeter is at most 130 centimeters, what is the greatest possible value for the width?
 
 A.
2w + 2 • (4w) < 130
 
 B.
2w + 2 • (4w) > 130
 
 C.
2w + 2 • (4w) ≤ 130
 
 D.
2w + 2 • (4w) ≥ 130

texaschic101 · Answer

P = 2L + 2W
L = 4W
P <= 130

2(4W) + 2W <= 130 or 2W + 2 * 4W <= 130 (C)
