ASSIGNMENT:
1. Prepare comparative income statements for the three inventory costing methods of , LIFO, and weighted average. Include a detailed cost of goods sold section as part of each statement. The company uses a periodic inventory system , and its income tax rate is 30%. (Round per unit costs to three decimals, but inventory balances to the dollar.)

2. How would the financial results from using the three alternative inventory costing methods change if QP had been experiencing declining costs in its purchases of inventory?

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

These are my results but they do not add up!!
