Answer:
Equivalent units using the weighted-average : Materials = 1,345 units, Conversion Costs = 1,078 units and FIFO methods : Materials = 1,000 units, Conversion Costs = 1,009 units.
Step-by-step explanation:
Weighted-average method
This method focuses on completed units and units in ending work in process
Materials = 900 x 100 % + 445 x 100 % = 1,345 units
Conversion Costs = 900 x 100 % + 445 x 40 % = 1,078 units
FIFO method
This method focuses on work done during the production period only
Materials = 345 x 0 % + 555 x 100% + 445 x 100 % = 1,000 units
Conversion Costs = 345 x 80 % + 555 x 100% + 445 x 40% = 1,009 units
Conclusion
Equivalent units using the weighted-average : Materials = 1,345 units, Conversion Costs = 1,078 units and FIFO methods : Materials = 1,000 units, Conversion Costs = 1,009 units.
