Assignment 12- Using your brain

Go here and answer the "extra credit" question in a blog entry titled "Assignment 12- Using my brain"

copy and paste...

At a rural cabin, you get water from a well using only a 4-gallon bucket and a 9-gallon bucket. In a single trip from the well to the cabin, what whole number gallon amounts of water could you bring back to the cabin?

There are no markings on the pails.  And, you can’t do any estimating or add any markings!

The easy ones are

4- fill up the 4-gallon bucket

9- fill up the 9-gallon bucket

13- fill up both buckets

... these blue words in your post.  Then answer the question.  This is for regular credit in this class.  You may collaborate with other students in this class to come up with all the answers.  Make sure that you explain all possible gallon amounts to get credit.
