x percent of y percent of z is decreased by y percent, What is the result? Pick one: A) (100xyz - xy^3z) / 1,000,000 *(-1/48) B) (xz - y) / 100 C) (xz - y) / 10,000 D) (xyz - 2y) / 100 E) (xyz - 2y) / 10,000
We're told that X percent of Y percent of Z is DECREASED by Y percent. We're asked for the result of all of this math.   IF....   X = 10   Y = 50   Z = 100   First, 50% of 100 = 50   Next, 10% of 50 = 5   Finally, 5 decreased by 50% of itself is 2.5   So we're looking for an answer that equals 2.5 when X=10, Y=50 and Z=100.   Answer A. (100xyz - xy^2z) / 1,000,000 = (5,000,000 - 2,500,000)/1,000,000 *(-1/48) = 2,500,000/1,000,000 = 2.5   This is a M(100xyz - xy^3z) / 1,000,000 *(-1/48)TCH   (100xyz - xy^3z) / 1,000,000 *(-1/48)
