Answer:
A.
Step-by-step explanation:
In order to find the cost of the wallpaper per square foot, we must do 700.92 divided by the area of the wallpaper.
Area = length times width
Area of wallpaper = 12*9=108
700.92/108 = 700.92/108 = 6.49
The cost per a square foot is $6.49, so the answer is A.
Hope this helps :)
