Pilar Chemicals has a mixing department and a refining department. Its process-costing system in the mixing department has two direct materials cost categories (chemical P and chemical Q) and one conversion costs pool. The following data pertain to the mixing department for July 2020:

Units

Work in process, July 1 0

Unit started 100,000

Completed and transferred to refining department 70,000

Costs

Chemical P $600,000

Chemical Q 140,000

Chemical costs 360,000

Chemical P is introduced at the start of operations in the mixing department, and chemical Q is added when the product is three-fourths completed in the mixing department. Conversion costs are added evenly during the process. The ending work in process in the mixing department is two-thirds complete.
