what is the minimum possible range in scores of the three test-takers?Three people each took 5 tests. If the ranges of their scores in the 5 practice tests were 18, 26 and 32.	Pick
A) 26
B) 32
C) 18
D) 20
E) 30
I simply looked at the 3 different possible scores for each individual test: 18,32,26   We have to find the minimum range:    32-18= 
<gadget id="calculator"> 32-18</gadget>
<output>14</output>
14   32-26= 
<gadget id="calculator">32-26</gadget>
<output>6</output>
6   26-18= 
<gadget id="calculator">26-18</gadget>
<output>8</output>
8   The find the minimum range, you have to make the set of the 5 scores as small as possible.   Which means that 4 of the 5 scores of each individual person is zero.   6*5= 
<gadget id="calculator">6*5</gadget>
<output>30</output>
30   Answer:30
<result>E</result>
