Answer:
12
Explanation:
skeins of yarn purchased = 11
Feets per skein = 660 feets
Total number of feets purchased = (11 * 660) = 7260 feets
To make a scarf :
1 scarf = 200 yards
Recall :
1 yard = 3 feets
Hence,
1 scarf = (200 *3) = 600 feets
Number of scarf that can be made :
Total feets of yarn / Number of feets per scarf
= 7260 / 600
= 12.1
Hence, number of scarfLee can make for shelter is 12 (nearest whole number)
