You are moving into a new apartment and realize you need a rug to cover the floor. You know a great local store that sells rugs of any dimension you want. They charge a fixed rate per square foot.
(a.) Your new place needs a 12 ft by 18 ft rug. You notice that these sides are 50% longer than the rug from your old place. What were the dimensions of the old rug?
(b.) You know that a 4 ft by 6 ft rug from the same place will cost you $16. How much should your new 12 ft by 18 ft rug cost you?
Extra Credit (5 points): When checking your email, you “coincidentally” get an ad for a website offering 12 ft by 18 ft rugs for $60. Should you go with this other company instead? Give your reasoning.
