The weighted average cost method is most commonly used in manufacturing businesses where inventories are piled or mixed together and cannot be differentiated, such as chemicals, oils, etc. Chemicals bought two months ago cannot be differentiated from those bought yesterday, as they are all mixed together.
What is a Gobo Root? Gobo is Japanese for burdock, which is a hairy taproot that can grow up to 4 feet in length. It originated in China where it was used as a medicine, and was then later introduced to Japan where it became a delicacy. The slender roots have a white flesh with brown covering that is edible after being scrubbed clean.
Burdock has long been considered a vegetable in Asian cooking. Known as Gobo, you may have seen the root in your local grocers and not even known that it was what we Americans consider a common weed. Burdock is a biennial, meaning that it grows for two years. The first year plants offer the roots.
