Question

You need 30 yards of yarn to crochet a small scarf. Cheryl bought a 100-yard ball of yarn and has already used 10 yards. Write and solve an equation to find how many scarves she can crochet if she plans on using the entire ball.

Answer 1

Cheryl can crochet 3 scarves using the entire ball of yarn.

Step-by-step explanation:

To find out how many scarves Cheryl can crochet using the entire ball of yarn, we need to subtract the amount of yarn she has already used from the total amount she bought. In this case, Cheryl bought a 100-yard ball of yarn and has already used 10 yards. So, she has 100 - 10 = 90 yards left. Since she needs 30 yards to crochet one small scarf, we can divide the remaining yards by the yards needed per scarf: 90 ÷ 30 = 3 scarves. Therefore, Cheryl can crochet 3 scarves using the entire ball of yarn.
