Answer: She will need 142 ft of curtain.
Step-by-step explanation:
Hi, first we have to convert the length of the curtain from inches to foot.
Since 1 inch = 1/12ft
For 24 inches:
24 inches x 1/12 = 2 ft
Since the company wants to make 71 curtains, we have to multiply the length of each curtain (2ft) by 71.
2ft x 71 = 142ft
She will need 142 ft of curtain.
