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 $600 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 $118,400, of which $50,912 is a variable cost. Required: 1.
