Jennifer has 84.5 yards of fabric to make curtains. she makes 6 identical curtains and has 19.7 yards of fabric remaining. How many yards of fabric does Jennifer use per curtain?

She uses 10.8 yards per curtain

Step-by-step explanation:

Let each curtain is of x yards,

Thus, the total fabric she used for 6 curtains = 6x yards,

Since, the remaining fabric she will have after making the curtains = 19.7 yards,

So, the total fabric she has initially = Fabric she used for 6 curtains + Remaing fabric

= (6x + 19.7) yards,

But, the total fabric she has initially = 84.5 yards,

⇒ 6x + 19.7 = 84.5

⇒ 6x = 64.8

⇒ x = 10.8

Hence, she uses 10.8 yards per curtain.
