Inorganic Chemicals (IC) processes salt into various industrial products. In July 2017 IC incurred joint costs of $100,000 to purchase salt and convert it into two products: caustic soda and chlorine. Although there is an active outside market for chlorine, IC processes all 800 ton of chlorine it produces into 500 tons of PVC (polyvinyl chloride), which is then sold. There were no beginning or ending inventories of salt, caustic soda, chlorine, or PVC in July. Informa. tion for July 2017 production and sales follows: w Home Insert Page Layout Formulas View A Data Review | Joint Costs PVC $100,000 Joint costs (costs of salt and processing to 2 splitoff point) Separable cost of processing 800 tons of 3 chlorine into 500 tons of PVC $20,000 Caustic Soda Chlorine PVC 1,200 800 800 6 Beginning inventory (tons) 7 Production (tons) 8 Transfer for further processing (tons) 9 Sales (tons) 10 Ending inventory (tons) Selling price per ton in active outside market 11 (for products not actually sold) 12 Selling price per ton for products sold 1,200 0 0 $ 75 $ 50 $ 200 1. Allocate the joint costs of $100,000 between caustic soda and PVC under (a) the sales value at splitoff method and (b) the physical measure method. 2. Allocate the joint costs of $100,000 between caustic soda and PVC under the NRV method. 3. Under the three allocation methods in requirements 1 and 2, what is the gross-margin per- centage of (a) caustic soda and (b) PVC? 4. Lifetime Swimming Pool Products offers to purchase 800 tons of chlorine in August 2017 at $75 per ton. Assume all other production and sales data are the same for August as they were for July. This sale of chlorine to Lifetime would mean that no PVC would be pro- duced by IC in August. How would accepting this offer affect IC's August 2017 operating income
