The cost of wallpaper used to cover all sides of the storage box is given by $3 per square foot
<h3>Cost of wallpaper per square foot</h3>
- length = 9 ft
- Width = 8 ft
- Height = 5 ft
Surface area of a box = 2(lh + wh + lw)
= 2(9×5 + 8×5 + 9×8)
= 2(45 + 40 + 72)
= 2(157)
= 314 square foot
- Total cost of wallpaper = $942
Cost of wallpaper per square foot = $942 ÷ 314 square foot
= $3 per square foot

The equation produces a straight line.
The answer is D because if you add 4 7/10 which is 4.7 and add 5 4/5 which is 5.8 it is 4.7 plus 5.8. That equals 10.5 which is equal to the answer of 10 1/2. If this is right could I possibly get brainliest?
