assembly takes place in the CPU Assembly Department.

Started into production. Total units to be accounted for 5,000 29,000 Units accounted for as follows: 30,000 work in process, May 31 (materials 75% complete, conversion 50% complete) Total units accounted fo 4000 Total Cost Cost to be accounted for: Work in process, May 1 Cost added in the department E 13.400 Cost accounted for as follows: 93.000 Transferred to the next department.
