Three people each took 6 tests. If the ranges of their scores in the 6 practice tests were 17, 28 and 35, 42 what is the minimum possible range in scores of the three test-takers?	Choices:
A) a 17  B) b) 28  C) c) 35  D) d) 45  E) e) 80
It is finding the minimum range between all their scores, if all test taker scores are between 0 and maximum range we will have:   A- 0 and 17   B- 0 and 28   C- 0 and 35   D-0 and 42   therefore the minimum range is 42, it cant be any lower however you play with the numbers.   d) 45
