rugs Emporium installs carpet for $80 plus $9.50 per square yard of carpet carpets 4 U charges $120 for installation and $7.50 p
mihalych1998 [28]

The area of the carpet must be <u>greater than 20 square yards</u> for which Rugs Emporium charges more than Carpets 4U.

<u><em>Explanation</em></u>

Suppose, the number of square yards of carpet is  x

Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for x square yards of carpet = (80+9.50x) dollar

Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for x square yards of carpet =(120+7.50x) dollar

If the Rugs Emporium charges more than Carpets 4U , then the inequality will be.....

80+9.50x>120+7.50x\\ \\ 9.50x-7.50x>120-80 \\ \\ 2x>40\\ \\ x>20

So, the area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.
