Final answer:
To find the cost of the carpet per square foot, divide the total cost of the carpet by the square footage of the room. The cost of the carpet per square foot is $1.49.
Step-by-step explanation:
To find the cost of the carpet per square foot, we need to divide the total cost of the carpet by the square footage of the room.
Given that the square footage of the room is 210 square feet and the total cost of the carpet is $312.50, we can determine the cost per square foot as follows:
Cost per square foot = Total cost of carpet / Square footage of the room
= $312.50 / 210 square feet
= $1.49 (rounded to two decimal places)
Therefore, the cost of the carpet per square foot is $1.49.
