Under the weighted-average method, what does an equivalent unit mean? Be sure to address whether equivalent units of work done means the same thing as units completed this period.

As Efrain Manufacturing produced bookshelves this month, its accountants were in contact with production managers to keep tabs on costs. The WIP Inventory-Assembly account had a beginning balance as follows: DM costs of $42,000 and conversion costs of $30,000.
