NEED HELP PLS

Hean's bedroom is 12 feet by 11 feet. She has chosen a carpet which costs $31.10 per square yard. This
includes installation. Determine her cost to carpet her room.

How much would she have saved if she went with the carpet that costs $28.60 per square yard instead?

12 x 12 = 144, her room is 144 square feet. One yard is three feet, making a square yard equal to 9 square feet. 144 divided by 9 is 16 square yards. Now we do 16 times the installation cost $28.10. So 16 x 28.10 = 449.6, or $449.60.

I hope this helps >:)
