# Exercise 4: Cost per equivalent unit – weighted average and FIFO method

Alpha Global Inc. produces a product known as Antacid-ZX – an over the counter medicine used to neutralize stomach acidity. The processing of Antacid-ZX is completed in three separate departments. The data belonging to first department for the month of March is given below:

The stages of completion of beginning and ending work in process inventories with respect to materials and processing were as follows:

Beginning work in process inventory:
Materials: 80%
Processing: 75%

Ending work in process inventory:
Materials: 60%
Processing: 20%

Required: Make a quantity schedule, compute the equivalent units of production and determine the cost per equivalent unit assuming Alpha uses the following methods of accounting for units and costs:

1. Weighted average method
2. FIFO method

## Solution

### 2. FIFO method

#### Quantity schedule and equivalent units

*Work required to complete gallons in work in process beginning inventory
Materials:
100% – 80% = 20%
40,000 × 20% = 8,000 gallons
