Three people each took 5 tests. If the ranges of their scores in the 5 practice tests were 17, 28 and 35, 45 what is the minimum possible range in scores of the three test-takers? Pick one.
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 45   therefore the minimum range is 45, it cant be any lower however you play with the numbers.   d) 45
