Final answer:
Option A). To find the cost of installing wall-to-wall carpeting in a room, find the area of the room by multiplying its length and width. Then, multiply the area by the cost per square foot of the carpeting.
Step-by-step explanation:
To calculate the cost of installing wall-to-wall carpeting in a room, you need to find the area of the room and then multiply it by the cost per square foot of the carpeting. The area of the room is found by multiplying its length by its width. In this case, the room is 12 feet long and 9.5 feet wide, so the area is 12 * 9.5 = 114 square feet.
Now, you can multiply the area by the cost per square foot of the carpeting. The cost per square foot is $14.99. So, the total cost of putting in wall-to-wall carpeting in the room is 114 * $14.99 = $1,709.86.
Therefore, the answer is A) $1,709.86.
