Answer:
The question is missing cost figures so it's not possible to determine the equivalent cost per unit
Step-by-step explanation:
More information is needed. However we can still determine the total equivalent units.
It is given that a total of 12000 units were completed and transferred out of department B for February. We're left with 6000 units in beginning work in process that are 50% complete. Thus 6000 x 50% = 3000 equivalent units in beginning work in process
75% of units in ending work in process are complete. Thus 75% x 8000 = 6000 equivalent units.
The total equivalent units for February will be 9000 + 12000 completed units which is 21000 units.
However we need additional costing information that is missing to complete the question.
