A manufacturing company makes two joint products, CP1 and CP2, in a common process. These products can be sold at the split-off point in an external market, or processed further in separate processes to produce products FP1 and FP2. Details of these processes are shown in the diagram. CP1 has a market price of $6 per kg and CP2 has a market price of $5 per kg. Relevant further processing costs are $2 per input kg in the process to make FP1 and $3 per input kg in the process to make FP2. Both FP1 and FP2 sell for $9 per kg. For each 10,000 kg input to the common process, how much additional profit is obtained by further processing each of the joint products instead of selling them at the split-off point?
