A rectangular-shaped carpet remnant that measures x feet by y feet is priced at $30. What is the cost of the carpet, in dollars per square yard? (9 square feet = 1 square yard) Choose the most appropriate option:	A) 30xy	B) 270/(xy)	C) xy/9	D) xy/30	E) 270xy
xy sq ft = $30   1 sq ft = $30/xy   multiplying by 9 on both side   9 sq ft = $270/xy   or 1 sq yard = $270/xy   Hence 270/(xy).
