Silk is purchased for $250 per square yard at the Silk Market. The silk is cut into patterns and made into s-size shirts - the excess silk is discarded (1/5 of the silk material). The area is 2 square yards in the pattern that makes 1 side of an s-size shirt. If 2 sides make one shirt, how much money is needed to buy silk to make x number of s-size shirts, in dollars?  Choices:	A) 2x	B) 15x/8	C) 850x	D) 1,250x	E) 3,000x/2
The initial cost for a square yard of silk is = $250.   It takes 2 square yards of silk to make one side of an s-size shirt, but 1/5 of the material is wasted in cutting the material into patterns. The cost is; therefore, (1 square yard)(1 - 1/5) = $250, and so, 1 square yard = $250(5/4) for useful silk.   Because it takes 2 square yards to make one side, and 2 sides to make one shirt:   (2)(2)($250(5/4) = $1,250 = cost 1 shirt.   So, x number of shirts cost $1,250x   Answer is 1,250x
