Final answer:
Processing product QI further after the split-off point leads to a financial disadvantage of $5,700 compared to selling it right away. It accounts for both the additional costs of processing and the projected increase in selling price. The correct option is $5,700.
Step-by-step explanation:
To answer the student's question, we need to calculate the financial outcome of both selling product QI at the split-off point and after further processing. Selling the product as-is at the split-off would generate total revenues of 2,300 units at $12 each, summing up to $27,600. The allocated joint costs are $28,300, so the net benefit is $27,600 - $28,300 = -$700 (a disadvantage).
If the product QI is processed further, there is an additional cost of $10,300, but the selling price increases to $14 per unit. The total revenue from selling the processed units is 2,300 units at $14 each, which equals $32,200. Deducting the additional processing costs and the allocated joint costs, the net benefit is $32,200 - ($10,300 + $28,300) = -$6,400.
Comparing both scenarios, the financial advantage (or disadvantage) is calculated by subtracting the net benefit of further processing from the net benefit of immediate sale after the split-off: -$6,400 - -$700 = -$5,700. Therefore, processing product QI further results in a financial disadvantage of $5,700 compared to selling it immediately after the split-off. The correct option is $5,700.
