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]
