When sending a rectangular package through the U.S. Postal Service, the combined length and girth (perimeter of the cross sectio
weqwewe [10]
Let W = width of package
Let H = height of package
Let L = length of package

The perimeter cab be one of the following:
P = 2(L + W),  or
P = 2(L + H)

The perimeter of the cross section cannot exceed 108 in.
When the width is 10 in, then
 2(L + 10) <= 108
 L + 10 <= 54
 L <= 44 in

When the height is 15 in, then
2(L + 15) <= 108
L + 15 <= 54
L <= 39 in

To satisfy both of these conditions requires that L <= 39 in.

Answer: 39 inches

Sweater regularly priced for $84 is placed on sale for $67.20. What is the percent discount?
creativ13 [48]
<h3>Answer:  20% discount</h3>

Work Shown:

amount saved = 84-67.20 = 16.80 dollars

Divide this over the original larger price to get 16.80/84 = 0.20 = 20%

Note how 20% of 84 = 0.20*84 = 16.80 to help check the answer.

Or we can say 0.80*84 = 67.20 which also helps confirm the answer.

The 0.80 is from the fact that you save 20% but still have to pay the remaining 80%
