We can solve for the cost per equivalent unit for materials by using the formula:
Cost per equivalent unit = (Beg. work in Process Costs + Costs added this period) / (Units completed this period + Units in Ending Work in Process)
From the given problem, we are given the values for the materials:
Beg. work in Process Costs = $7,000
Costs added this period = $36,000
Units completed this period = 10,000 units
Units in Ending Work in Process = 4,000 units
Therefore:
Cost per equivalent unit = (7000 + 36000) / (14000)
Cost per equivalent unit = $3.07
Therefore the cost per equivalent unit is about $3 under FIFO method.
