1. You have that:
 - The new client who needs 4 drapes.
 - Each dreape will need to be 8 feet by 5 feet. Therefore, the perimeter will be:
 P1=8 ft+8 ft+5 ft+5 ft
 P1=26 ft
 - You must add an additional 6 inches on top and bottom. Therfore, the perimeter will be:
 1 inch=0.0833 ft
 6 inches=0.499 ft≈0.50 ft
 P2= 2(0.50 ft++0.50 ft+8 ft+8 ft)
 P2=34 ft
 - Thefore, the total perimeter of the drape will be:
 Pt=26 ft+34 ft
 Pt=60 ft
 - The perimeter of 4 drapes will be:
 =60 ftx4
 =240 ft
 - The problem says that the store only has 6 linear yards of material. Therefore:
 6 yards=18 ft
 The answer is: It is not enough to make all drapes, because you need 240 ft of material and the store only has 18 ft.
