You want to have your carpet cleaned in your living room which measures 12’ by 14’. Company A charges $2.75 per square foot and

Sonja [21]

Answer: Company B

Step-by-step explanation:

First we must calculate the area of the carpet. Variable A represents area.

$14*12=A$

$A=168$

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.

$168*2.75= Company A\\$

Company A charges, $462, while Company B will charge $450 for the one room.

This means Company B has the better price.
