Answer: Company B
Step-by-step explanation:
First we must calculate the area of the carpet. Variable A represents area.


So the area of the carpet is 168 square feet.
To find what company A will charge we will multiply the 168 by 2.75 they charge per square foot.

Company A charges, $462, while Company B will charge $450 for the one room.
This means Company B has the better price.
