Comment on the problem

In order to give a numerical answer, we have assumed the problem statement to be "... bought two gallon cartons ...". This is a precise quantity.

The wording here indicates the purchase of an unknown number of two-gallon cartons. Each such carton would hold 256 fluid ounces, but it doesn't say how many Noelle bought.

translate k to n and reflect across the line containing jk.
