Final answer:
Without the necessary monthly purchase data, it is impossible to calculate the cost of goods sold (COGS) and ending inventory using the FIFO method. The proper calculation requires a detailed record of each month's purchases to determine the costs of the sold inventory and the value of remaining stock.
Step-by-step explanation:
Calculation of Cost of Goods Sold and Ending Inventory using FIFO
The question involves calculating cost of goods sold (COGS) and the cost of ending inventory using the First-In, First-Out (FIFO) method for inventory accounting. Under FIFO, it is assumed that the oldest inventory items are sold first. To calculate the COGS and ending inventory, we start with the initial inventory and account for purchases and sales throughout the year.
However, the question as presented lacks specific monthly purchase information, which would be necessary to accurately execute these calculations. Therefore, I will provide a general approach based on the initial data provided.
Initial inventory: 4,000 units at $25 each
Total initial inventory value = 4,000 units * $25/unit = $100,000
On December 31, the cumulative units sold are given as 40,712, and the remaining units on hand are 4,048. If no additional units were purchased throughout the year (which is unlikely in practice), the COGS would be:
COGS = (Initial inventory units - Ending inventory units) * Cost per unit
COGS = (4,000 units - 4,048 units) * $25/unit
However, this calculation is incorrect since we cannot have negative COGS or sell more units than the starting inventory without additional purchases.
Without monthly purchase data, we cannot accurately calculate the COGS or the ending inventory value using FIFO. The correct approach requires detailed monthly purchase data to track the cost of items sold and the remaining inventory costs as the year progresses.
