Explanation:
Equivalent units of production
Materials = 3,500 x 0% + 21,200 x 100% + 2,650 x 100% = 23,850
Conversion Cost = 3,500 x 20% + 21,200 x 100% + 2,650 x 80% = 24,020
Cost per equivalent units of production
Materials = $636,100 ÷ 23,850 = $26.67
Conversion Cost = $636,100 ÷ 24,020 = $26.48
Total = $26.67 + $26.48 = $53,15
Cost allocated to units transferred and to those still in process
Transferred to Assembly = Â 24,700 x $53,15 = $1,312,805
Ending WIP = 2,650 x $26.67 + 2,120 x $26.48 = $126,813
