Assume the following: WIP, beginning 1,500 units (100% complete as to direct materials, 60% complete as to conversion costs) Started 7,500 units during the period Total spoilage is 800 with normal spoilage is calculated to be 250 units Completed and transferred out during the period 7,000 units WIP, ending 1,200 units (100% complete as to direct materials, 40% complete as to conversion costs) Spoiled units 800 and inspection happens when the process is 20% complete All materials are added at the start of the process Under the weighted average method, would would be the equivalent units of work done for the period? O A. 7,640 O B. 7,000 O C. 1,200 OD. 1,730
