There are three people in lee’s family. The range if their shoe sizes are 3. Two people in her family wear size 6. Lee’s size is not 6 or 3. What is Lee’s shoe size?

I would say 9

Step-by-step explanation:

range is the difference between the largest and the smallest values in a data set.  the range in this case is 3. so, we have to either add to 6 or subtract from 6.

but we've been told that Lee's shoe size is not three so it 6 + 3 = 9.

hope this helps

i'm pretty sure the answer is a. decreases with increase in
