Final answer:
Equivalent units for direct materials are 70,000 and for conversion costs are 56,200. The unit cost for direct materials is $0.55, for conversion costs is $1.10, and the total unit cost is $1.65. If candy wrappers are added at a cost of $4,700, the new total unit cost becomes $1.72 per unit.
Step-by-step explanation:
Calculating Equivalent Units and Costs in Production Process
To calculate the equivalent units for each input category, we consider that materials are added at the beginning of the process and thus all units will have 100% of the material costs applied.
For conversion costs, the equivalent units are the units completed plus the equivalent units for the ending work in process (EWIP), calculated as 40% of the 23,000 units in EWIP:
Conversion Costs: 47,000 units (completed) + 9,200 units (40% of 23,000 EWIP) = 56,200 equivalent units
For direct materials: $38,500 / 70,000 units = $0.55 per unit.
For conversion costs: $61,820 / 56,200 units = $1.10 per unit.
The total unit cost is the sum of the unit direct materials cost and the unit conversion cost, equaling $1.65 per unit.
If a different type of material (candy wrapper) was added at the end of the process, costing an additional $4,700, this cost would be divided by the total number of units to find the additional cost per unit. Therefore, the additional unit cost for candy wrappers would be $4,700 / 70,000 units = $0.07 per unit, making the new total unit cost $1.65 + $0.07 = $1.72 per unit.
