Trevor Mills operates a single plant that produces agricultural feed. The production process begins with the addition of materials. Here's a summary of the work-in-process for December: - **Beginning Inventory**: The month started with 36,000 partially complete units, which were 10% complete in terms of conversion costs. - **Units Started**: Throughout December, production started on 97,000 units. - **Units Transferred Out**: A total of 93,000 units were transferred out in December. - **Ending Inventory**: The month ended with an inventory of 40,000 units, which were 62% complete in terms of conversion costs. The task is to calculate the equivalent units for materials and conversion costs for December using the FIFO method. This method considers the first units that entered production to be the first ones transferred out. It's a common approach in cost accounting and provides a detailed view of inventory flow
