Answer:
16.55 Dollars
Explanation:
First we calculate the cost Equivalent units for material.
Materials
Percentage Units
Units completed and transferred 100 900
Ending work in process inventory 90 2250
2500x90%=11250
Cost equivalent Equivalent units 11250
Now we calculate the cost per equivalent unit for materials
Cost in work at process in beginning 13500
Cost added during month 172600
Total cost 13250+172600=186100
Cost per unit can be achieved by dividing the total cost by cost of equivalent unit
186100/11250= 16.55 Dollars
