Three people each took 4 tests. If the ranges of their scores in the 4 practice tests were 17, 28 and 35, what is the minimum possible range in scores of the three test-takers?  Choose the correct choice.
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   therefore the minimum range is 28, it cant be any lower however you play with the numbers.   b) 28
