Chemkill manufacturing produces a chemical pesticide and uses process costing. there are three processing departments -mixing, refining, and packaging. on january 1, the first department-mixing--had a zero beginning balance. during january, 45,000 gallons of chemicals were started into production. during the month, 35,000 gallons were completed, and 10,000 remained in process, partially completed. in the mixing department, all direct materials are added at the beginning of the production process, and conversion costs are applied evenly throughout the process. during january, the mixing department incurred $50,000 in direct materials costs and $211,800 in conversion costs. at the end of the month, the ending inventory in the mixing department was 60% complete with respect to conversion costs. the weighted average method is used. the total cost of the chemical pesticide in ending inventory was places, and your final answer to the nearest dollar.) (round any intermediate calculations two decimal a. $42,120. b. $50,000. c. $211,800.d. $261,800.
