Question

Justin is sewing baby blankets to donate to the local hospital. Each blanket requires 4.25 yards of fabric, and he wants to make 10 blankets. Since each blanket takes approximately 4 yards of fabric, Justin estimates that he needs to buy 40 yards of fabric. Will Justin have enough fabric to make the blankets? Explain your answer.

Answer 1

It's obvious that Justin underestimated the amount of cloth required.

Explanation:

Total fabric needed = 10 blankets * 4.25 yards / blanket = 42.5 yards.

He however does estimate that each blanket requires about 4 yards of cloth. He determines that he requires the following for 10 blankets:

Estimated fabric needed = 10 blankets * 4 yards / blanket = 40 yards.

Let's now contrast the predicted fabric need (40 yards) with the actual requirement (42.5 yards):

Estimated fabric needed: 40 yards

Actual fabric needed: 42.5 yards

Since Justin calculates that he needs 40 yards of cloth but the real amount needed is 42.5 yards, it is clear that Justin's calculation is wrong. Not enough fabric would be available for him to sew all ten baby blankets.

Justin needs to make sure that he has enough fabric to meet the actual demands for all 10 blankets in order to make them all. To ensure that he has enough fabric to finish his project, he should think about purchasing at least 42.5 yards of it.

Answer 2

No, he needs 42.5 yards of fabric

Explanation:

Yes, 10 x 4 is 40, but the actual amount need to make 10 blankets is

10 x 4.25 = 42.5 yards of fabric. He will not have enough to make 10 blankets if he buys 40 yards of fabric.
