Shawna needs 1,370 yards of yarn to knit a blanket. She buys 8 balls of yarn, which are each 185 yards long. Shawna hopes there will be enough leftover yarn to knit a scarf for her younger brother. A child's scarf takes 125 yards of yarn.

Question

Shawna will have
yards of yarn left after she knits the blanket.
Is that enough to knit the scarf?

Answer 1

First, let's calculate the total amount of yarn Shawna bought:

\[ \text{Total yarn} = \text{Number of balls} \times \text{Yards per ball} = 8 \times 185 \text{ yards} = 1480 \text{ yards} \]

Next, we will determine how much yarn Shawna will have left after she knits the blanket:

\[ \text{Yarn left} = \text{Total yarn} - \text{Yarn needed for the blanket} = 1480 \text{ yards} - 1370 \text{ yards} = 110 \text{ yards} \]

Now, we will check if this leftover yarn is enough to knit the scarf:

\[ \text{Yarn needed for the scarf} = 125 \text{ yards} \]

Since Shawna has 110 yards left, which is less than the 125 yards required for the scarf, we can conclude:

Shawna will have 110 yards of yarn left after she knits the blanket, which is not enough to knit the scarf.
