Madeline has eight dogs. The mean weight of the lightest six is 40 pounds. The mean weight of the heaviest six is 55 pounds. What is the greatest possible range of weights of her dogs?
This was posted earlier.....I do not know if anyone has tried to answer it....I do not yet have an idea.
I'm thinking it is something like 2.5 to 92.5 pounds....not sure....
(5 @47.5 + 2.5)/6 = 40 (5 at 47.5+ 92.5)/6 = 55
Good Job EP, I got the answer of 90 (92.5-2.5) as well!
I'm pretty sure that this is correct, Nice Try!
