Hi there!

First, we need to find the area of the wallpaper.

42 × 25.5 = 1071

Now, we divide 771.12 by 1071.

771.12 ÷ 1071 = 0.72

So, the wallpaper costs 0.72 dollars per square foot.

Hope this helps!

Answer:

The cost of the wallpaper was 0.72 dollars per square foot.

Step-by-step explanation:

First we calculate the area of the wallpaper in square foot:

A = 42 ft x 25.5 ft = 1071 ft^2

Then we divide the total cost by the area:

C/A= $771.12 / 1071 ft^2 = 0.72 $/ft^2
