The answer is <span>B. |w – 48| ≤ 8.
w - the weight of the box
</span>The weight of the box must be within 8 pounds: w ≤ 8
The weight of the box must be within 8 pounds of a standard lifting weight of <u>48 pounds</u>: <span>|w – 48| ≤ 8</span>
2L+2W=157.5
L=W-30
2(W-30)+2W=157.5
2W-60+2W=157.5
+60 +60
4w=217.5
W=54.4(.37 rounded to nearest tenth)
L=24.4
Slope = rise/run = 10/50 = 1/5
