Problem: Assume that the shell-creating process has 8,000 units in BWIP, 20% complete. During the year, 50,000 units were completed and transferred out. (Note: All 50,000 units were sold; no other units were sold.) The EWIP inventory had 8,000 units, 30% complete. Compute the value of the shell-creating department's EWIP. What additional assumptions had to be made?
