Answer:
1.3
Step-by-step explanation:
5x+7x+6-26=29
12x-20=29
12x=29-20
12x=9
x=1.3
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>
