a percent of b percent of c is decreased by y percent. What is the result?	Choose the correct choice from the following:
A) (100abc - ab^2c) / 1,000,000	B) (ac - b) / 100	C) (ac - b) / 10,000	D) (abc - 2b) / 100	E) (abc - 2b) / 10,000
We're told that a percent of b percent of c is DECREASED by Y percent. We're asked for the result of all of this math.   IF....   a = 10   b = 50   c = 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 a=10, b=50 and c=100.   Answer A. (100abc - ab^2c) / 1,000,000 = (5,000,000 - 2,500,000)/1,000,000 = 2,500,000/1,000,000 = 2.5   This is a M(100abc - ab^2c) / 1,000,000TCH   (100abc - ab^2c) / 1,000,000
