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.

Respuesta :

Cheryl can make 3 scarves with the ball of yarn left

Cheryl has used out of the ball of yarn. So the amount of scarves she can make with the yarn has reduced

Yards left = 100 - 10 = 90 yards

Number of scarves she can make with the yards left = yards left / yards needed to crochet a scarf

90 / 30 = 3 scarves
