6. Thomas Company, a new firm, manufactures two products, Q and R, in a common process. The joint costs amount to $42,000 per batch of finished goods. Each batch results in 10,000 liters of output, of which 70% are Q and 30% are R. The unit selling price for Q is $4 and for R is $8 at the split-off point. However, the two products are processed beyond the split-off point, with Thomas incurring the following separable costs: Q, $0.50 per liter; R, $1.00 per liter. After the additional processing, the selling price of Q is $6.50 per liter, and the selling price of R is $12.00 per liter. Required: A. Determine the proper allocation of joint costs if the company uses the sales value method. B. Assume that Thomas sold all of its production of Q and R during the current accounting period. Compute Thomas's final net profit (loss) assuming again that the company uses the sales value method for the allocation of joint costs. . C. Assume that Thomas sold all of its production of Q and R during the current accounting period. Compute Thomas 's incremental net profit. (9 Points)
