Dear Tutor,

Could you please help me with the calculations below? Somehow I cannot get the correct answers.

Thanks a lot in advance!

Multi-stage production process:

Stage	Inventory stock from the prior production stage at the beginning of the period	Production volume of each stage during the production	Total primary costs of each production stage (in )
Opening balance (in units)	Valuation of opening balance (in per unit)	Input quantity used of preliminary product	Output quantity of finished goods
1	-	-	-	800	400
2	600	1.0	800	600	800

a) Please calculate the cost per unit at stage 1. If necessary, assume thatLIFOis used in /unit

b) Please calculate the cost per unit at stage 2. If necessary, assume thatLIFOis usedin /unit

c) Please calculate the cost per unit at stage 1. If necessary, assume thatFIFOis usedin /unit

d) Please calculate the cost per unit at stage 2. If necessary, assume thatFIFOis used in /unit
