Multiple Choice
Which of the following formulas correctly represents the relationship between inventory and cost of goods sold (COGS) under both perpetual and periodic inventory systems?
Step 1: Understand the concept of Cost of Goods Sold (COGS). COGS represents the direct costs attributable to the production of goods sold by a company. It includes the cost of materials and labor directly used to create the goods.
Step 2: Recall the formula for COGS under both perpetual and periodic inventory systems. The formula is derived from the inventory equation: Beginning Inventory + Purchases - Ending Inventory = COGS.
Step 3: Analyze the components of the formula: Beginning Inventory represents the inventory at the start of the period, Purchases represent the goods bought during the period, and Ending Inventory represents the inventory remaining at the end of the period.
Step 4: Compare the given formulas to the standard inventory equation. The correct formula should align with the inventory equation: COGS = Beginning Inventory + Purchases - Ending Inventory.
Step 5: Eliminate incorrect options by checking whether they violate the inventory equation. For example, formulas that add Ending Inventory instead of subtracting it or subtract Beginning Inventory instead of adding it are incorrect.
