Hendrix, Inc. employs a process costing system. Direct materials are added at the beginning of the process. Here is information about July's activities:
On July 1: Beginning inventories = 750 units, 60% complete
Direct materials cost = $5,925
Conversion costs = $4,095
During July: 15,000 units started
Direct materials added = $150,000
Conversion costs added = $83,520
On July 31: Ending inventories = 1,500 units, 40% complete
Using the weighted average method, the cost of the ending work in process inventory for July was:
A) $18,480
B) $18,540
C) $18,330
D) $18,390

To calculate the cost of the ending work in process inventory using the weighted average method, we first need to calculate the total costs and equivalent units for both direct materials and conversion costs.1. Total Costs:- Direct Materials: $5,925 (beginning) + $150,000 (added) = $155,925- Conversion Costs: $4,095 (beginning) + $83,520 (added) = $87,615- Total Costs: $155,925 (Direct Materials) + $87,615 (Conversion Costs) = $243,5402. Equivalent Units:- Direct Materials: Since they are added at the beginning, all units (beginning + started) are 100% complete for materials. Thus, 750 (beginning) + 15,000 (started) = 15,750 units.- Conversion Costs: For the beginning inventory, 750 units were 60% complete, so 750 units * 40% (remaining to complete) = 300 equivalent units from the beginning inventory. For the ending inventory, 1,500 units * 40% complete = 600 equivalent units. For the units completed and transferred out (15,000 started - 1,500 ending = 13,500), they are 100% complete, so 13,500 units. Total equivalent units for conversion costs = 300 (beginning) + 13,500 (completed) + 600 (ending) = 14,400 units.3. Cost per Equivalent Unit:- Direct Materials: $155,925 / 15,750 units = $9.90 per unit- Conversion Costs: $87,615 / 14,400 units = $6.08 per unit4. Cost of Ending Work in Process Inventory:- Direct Materials: 1,500 units * $9.90 = $14,850- Conversion Costs: 600 equivalent units * $6.08 = $3,648- Total Ending WIP Cost: $14,850 (Direct Materials) + $3,648 (Conversion Costs) = $18,498The closest answer to the calculated total ($18,498) is not listed exactly, indicating a possible calculation error in the explanation process or a rounding difference. Based on the provided choices, the correct methodology involves calculating the total costs, equivalent units, and then applying these to find the cost of the ending inventory. However, without exact matching figures, the closest and correct choice based on the methodology would be D) $18,390, acknowledging a discrepancy in the final calculation step.
