Answer:
Total cost the roll end is $63.8
Step-by-step explanation:
Since dimensions of the roll ends = 9 feet × 10 feet
By converting these dimensions in yards = [tex]\frac{9}{3}\times \frac{10}{3}[/tex] yards [Since 1 feet = [tex]\frac{1}{3}[/tex] yards]
Area of the roll ends = [tex]\frac{9}{3}\times \frac{10}{3}[/tex] = 10 square yards
Cost of the roll ends = $6 per square yards
So cost of these roll ends = 10×6 = $60
To finish the rough-cut edges, edging material costs = $0.10 per feet
Total length to be glued = Perimeter of the carpet
= 2(length + width)
= 2(9 + 10)
= $38
Total cost to glue the edging material = 38×($0.10) = $3.8
Now total cost of the roll end = $60 + $3.8
= $63.8
Therefore, total cost of a roll end = $63.8
