The answer to this problem is 12. If you want me to write it out I can
Basically, this problem is going to require you to solve for the area and multiply it with the given cost unit.
Area = Length*Height
Area = 100 ft * 8 ft = 800 ft²
Total Cost = (Unit Cost)(Area)
Total Cost = ($2/ft²)(800 ft²)
<em>Total Cost = $1,600</em>
10 and -7 times each other equals -70.
10 plus -7 equals 3.
Hope this helps you! (:
