Sarah has 4 pieces of yarn that are 6 yards each. She uses 9 pieces of yarn that are each 2 feet long. How much yarn does Sarah have left?

54 feet of yarn

Step-by-step explanation:

We have a conversion rate of

1 yard = 3 feet

Sarah has 4 pieces of yarn that are 6 yards each.

Hence,

1 yard = 3 feet

6 yards = x

Cross Multiply

x = 6 × 3 feet

x = 18 feet

Therefore, 4 pieces of yarn are 18 feet each

Hence, total feet of yarn above = 4 × 18 feet = 72 feet

She uses 9 pieces of yarn that are each 2 feet long.

Total feet of yarn here is:

9 × 2 feet = 18 feet of yarn

Therefore, the amount of yarn Sarah have left is calculated as:

72 feet - 18 feet

= 54 feet of yarn

the answer is y = 11.54
