Each scarf requires 39 yard yarn. To crochet 'x' scarf would require 30x yard of yarn.

She has 100-10 yard yarn remaining. if she intends to use all her remaining yard. then

Set the yarn required = yarn that is available

30x = 100 - 10

30x = 90

x = 90/30

x = 3

Hence she can crochet 3 scarves.
