uses a periodic inventory system, and its income tax rate is 30%.

2. How would the financial results from using the three alternative inventory costing methods change

if the company had been experiencing decreasing prices in its purchases of inventory?

3. What advantages and disadvantages are offered by using (a) LIFO and (b) FIFO? Assume the continuing trend of increasing costs.
