A. $0.60

Step-by-step explanation:

The prices for which the carpets were sold are

1) 100 square feet for $67

2) 200 square feet for $130

3) 400 square feet for $240

4) 800 square feet for $504. We would determine the unit cost per square foot for each of them. It becomes

1) 1 square feet costs 67/100 = $0.67

2) 1 square feet costs 130/200 = $0.65

3) 1 square feet costs 240/400 = $0.6

4) 1 square feet costs 504/800 = $0.63

The unit cost per square foot of carpet for the worst deal is $0.6
