Answer:
If Pernell Company had used the first-in, first-out (FIFO) inventory valuation method, their cost of goods sold (COGS) would have been $50,000 less during 2016.
Since the company uses the last-in, first-out method, its inventory value for 2016 was $50,000 higher than if it had used the FIFO method. This type of situations are common since the COGS tend to increase over time.
