For a certain set, the value range of its members is 96.8. A new set is created from the members of the old set as follows: 12 is subtracted from a member of the old set, and the result is divided by 4. The resulting value is a member of the new set. If this operation is done for each member of the old set, what is the range of values of the members of the new set? Choose one:	A) 21.2	B) 24.2	C) 36.3	D) 48.4	E) 96.8
Let x and z be the smallest and largest of the original set, respectively.   z - x = 96.8   The smallest and largest members of the new set will be (x-12) / 4 and (z-12) / 4.   Then the range is (z-12) / 4 - (x-12) / 4 = (z-x) / 4 = 96.8 / 4=
