Assume the following: WIP.beginning 4500 units (100% complete as to direct materials, 40% complete as to conversion costs) Started 12,500 units during the period Total spoilage is 800 with normal spoilage is calculated to be 350 units Completed and transferred out during the period 10.000 units WIP, ending 6200 units (100% complete as to direct materials, 50% complete as to conversion costs) Spoiled units 800 and inspection happens when the process is 30% 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? Select one: O A. 6200 O B. 9405 o 13,340 OD 10,000
