    Its in a textbook so I'm sure there is enough info to figure it out. Let me re-read it to see if I copied it right...

    well you could assume that each item would have to be the same price.... you could test and check... like you can take the 20-4.92 to get 15.08 then just divide that by a number between 2-8 that would have the same price...

    It would be 4 items.. since you can take the 15.08 and divide it by 4 and you get that each item costs 3.77 which would give you back 4.92 in change from the 20

    If you divide the 15.08 by any other number between 2-8 you will get more than 2 decimal places. thus 4 is the answer

    A sample of legal costs ( in thousands of dollars) for school districts for two recent consecutive years is shown. At a = 0.05 is there a difference in the costs? Suggest a reason for the difference, if one exists. Year 1 / 108, 36,65, 108, 87, 94, 10, 40 Year 2 / 138, 28, 67, 181, 97, 126, 18, 67
