Hello

A small correction :

1 yard = 3 feet (Not 9)

So 1 square yard = 9 square feet

So here area is xy square feet = xy/9 sq yard.

For xy/9 sq yard the cost is 50$

Therefore for one square yard the cost would be xy/(9*50) = xy/450.

A small correction in the above post the answer would indeed be

1/(xy/450) = 450/xy .

Here is another way of looking at it:

Area = xy
Price = 50
Price per sqr. foot = 50/xy
One sqr. yard = 9 sqr. ft.

Total Cost of the Carpet is:

(50/xy)(9) = 450/xy

I didn't recognize "Test Code (number)" as a source so I went looking for it. What I found appear to be illegally reproduced and distributed questions from GMAC.

Don't involve us in that, and use good sense when you are elsewhere on the web.
