Nathan Company produces three products (A, B, and C) in a single joint process. All of the products are salable immediately upon split-off. Alternatively, any of the products could be processed further and sold at a higher price. Cost and price information is as follows:

Product price at split - off additional processing cost price after processing unit volume

A $10 $10,000 $12 10,000

B $15 $25,000 $18 5000

C $20 $50,000 $30 8000

The decision that would maximize profits would be:

a. Product A sell now; Product B process further; and Product C sell now

b. Product A process further; Product B process further; and Product C process further

c. Product A process further; Product B sell now; and Product C process further

d. Product A sell now; Product B sell now; and Product C sell now
