Answer:
180 feet
Step-by-step explanation:
The length of each curtain = 48 inches. Let the length of the curtain in feet be represented by x.
But,
1 inch = 12 feet
So that,
48 inches = x feet
⇒ x = 
= 4
Thus,
48 inches = 4 feet
The number of feet of fabric needed for 45 curtains can be determined as:
45 x 4 feet = 180 feet
Therefore, 180 feet of fabric would be needed to make 45 curtains.
80-45+5+2=42
Your answer is 42
To find that , divide the estimate by the actual weight and multiply by 100.
8/6*100=133.33%(rounded)
Therefore the percent error is 133.33%.
