If carpet is 11.26 per sq yard and the carpet is 12' width how much is it per lineal foot?

Every 9 inches of a roll with a 12-foot width is a square yard. This means every lineal or running foot of 12-foot wide carpet is 1 1/3 square yards of carpet. If carpet is $11.26 per square yard, a running foot of our carpet on the roll would cost about $15. The actual answer is $15 and 1 & 1/3 cents a lineal foot.
