Problem 7-48 (Algo) Joint Products; By-Products (Appendix) [LO 7-6, 7-7] The Marshall Company has a joint production process that produces two joint products and a by-product. The joint products are Ying and Yang, and the by-product is Bit. Marshall accounts for the costs of its products using the net realizable value method. The two joint products are processed beyond the split-off point, incurring separable processing costs. There is a $1,900 disposal cost for the byproduct. A summary of a recent month's activity at Marshall is shown below: Total joint costs for Marshall in the recent month are $256,600, of which $110,338 is a variable cost. Required: 1. Calculate the manufacturing cost per unit for each of the three products. (Round manufacturing cost per unit answers to 2 decimal places.) 2. Calculate the total gross margin for each product
