Answer:

C. [tex]\$340[/tex]

Step-by-step explanation:

Given wallpaper costs [tex]\$1.25[/tex] per square foot.

Also, the dimension of the room is [tex]17\ ft[/tex]long by [tex]16\ ft[/tex] wide.

First, we will find the area of the room.

The room is in a rectangular shape.

So, the area of rectangle would be

       [tex]length\times width\\=17\times 16\\=272\ ft^2[/tex]

Now, we will multiply this area with the cost of wallpaper.

As the cost of wallpaper is $1.25 per square foot.

The total cost of wallpaper for [tex]272\ ft^2[/tex] would be [tex]272\times 1.25=\$ 340[/tex]
