San Jose, Inc., uses a weighted-average process costing system. All materials are introduced at the start of manufacturing, and conversion cost is incurred evenly throughout production. The company started 70,000 units during May and had the following work-in-process inventories at the beginning and end of the month:

May 1 30,000 units, 40% complete

May 31 24,000 units, 25% complete

Assuming no spoilage or defective units, the total equivalent units used to assign costs for May are

Materials.... Conversion Cost

Answer (D) is correct.
San Jose had 30,000 units in beginning work-in-process inventory and
started 70,000 during the month, for a total of 100,000 units to be
accounted for. Since all materials are introduced at the start of
manufacturing, all 100,000 units are 100% complete with respect to
materials costs. Equivalent units of production for conversion costs can
be determined as follows:
Beginning WIP 30,000 units × 100% = 30,000
Started and completed 46,000 units × 100% = 46,000
Ending WIP 24,000 units × 25% = 6,000
Totals 100,000 units 82,000
