If an item that originally sold for z dollars was marked up by x percent and then discounted by y percent, which of the following expressions represents the final price of the item?	Select the correct option:	A) (10,000z + 100z(x – y) – xyz)/10,000	B) (10,000z + 100z(y – x) – xyz)/10,000	C) (100z(x – y) – xyz)/10000	D) (100z(y – x) – xyz)/10000	E) 10000 /(x – y)
Z * (1+(x/100)) * (1-(y/100))   Z* (100+x/100) * (100-y/100)   (100Z + ZX)/100 * (100-y/100)   [10,000Z + 100 ZX - 100 ZY - XYZ] /10,000   [10,000Z +100Z (X - Y) - XYZ] / 10,000   Choice (10,000z + 100z(x – y) – xyz)/10,000
