The joint cost to produce Products 1A, 2A, 3A and 4A is $4,000. Each of these products can either be sold at the end of the joint production process, or can be processed further into 1B, 2B, 3B and 4B.

Production and selling information is as follows:

Product Name	Product 1A		Product 2A		Product 3A		Product 4A
Batch size (kg)	30		20		6		4
Sales Value ($ per kg)	100		50		2		0.5
If further processed:
processed from:		Product 1A		Product 2A		Product 3A		Product 4A
processed into:		Product 1B		Product 2B		Product 3B		Product 4B
Additional costs per batch ($)		50		130		120		10
Final batch size (kg)		29		15		6		3
Final Sales value ($/kg)		120		200		100		6

For example, at the end of the joint production process, there are 30 kg of Product 1A produced, and each kg of Product 1A sells for $100/kg. The 30kg batch of Product 1A can either be sold at this point for $3,000 (30kg x $100/kg) or the batch can be further processed into a batch of Product 1B at an additional cost of $50. This will produce a 29kg batch of Production 1B that sells for $120/kg for a total sales value of $3,480 (29kg x $120/kg).

Required:

Part A Assuming that none of the products are byproducts, calculate the how much of the $4,000 joint cost should be allocated to each product using the four methods discussed in class.

Part B Allocate the $4,000 joint cost assuming using the Net Realizable Value method and assuming that product 3 and product 4 are both byproducts. (hint: first determine if 3A should be processed further in 3B, and if 4A should be processed further into 4B)
