AcuBlade Castings Inc. casts blades for turbine engines. Within the Casting Department, alloy is first melted in a crucible, then poured into molds to produce the castings. On May 1, there were 700 pounds of alloy in process, which were 30% complete as to conversion. The Work in Process balance for these 700 pounds was $74,410, determined as follows: Direct materials (700 x $100) $70,000 Conversion (700 x 30% x $21) 4,410 $74,410 During May, the Casting Department was charged $633,600 for 6,600 pounds of alloy and $53,520 for direct labor. Factory overhead is applied to the department at a rate of 150% of direct labor. The department transferred out 6,800 pounds of finished castings to the Machining Department. The May 31 inventory in process was 20% complete as to conversion. a1. Prepare the May journal entry for the Casting Department for the materials charged to production.

For complete understanding lets first make EPU (Equivalent Production Unit)

                                                             Direct Material     Conversion

Units completed &transferred out         6,800                      6,800

Closing WIP                                               500                        100(500*20%)

Total units                                                7,300                       6,900

Closing WIP units = Opening WIP +During the year - units completed

                              = 700                 +     6,600           - 6,800

                              =500 units

On the basis of weighted average method following will be cost per unit:

Total Direct material cost/unit = (70,000 + 633,600)/7,300  = 96.3835

Total conversion cost/unit =(4,410+53,520+80,280(53,520*150%))/6,900=20.0304

Therefore, following would be the entries

WIP                      767,400

Material                               633,600

Conversion                          133.800 (53,520+80,280)

Finished goods    791,615 (96.3838+20.0304)*6,800

WIP                                        791,615

Working for closing unit

Material (500*96.3835) = 48,191

Conversion (500*20%*20.0304) = 2003.043
