Please explain how to do specific identification, weighted average, and LIFO.

Laker Company reported the following January purchases and sales data for its only product. For specific identification, ending inventory consists of 180 units from the January 30 purchase, 5 units from the January 20 purchase, and 15 units from beginning inventory. Date January 1 January 10 January 20 January 25 January 30 Activities Beginning inventory Sales Purchase Sales Purchase Totals Assume the perpetual inventory system is used. Required: Units Acquired at Cost @ $6.00 = $5.00 = @ $ 4.50 = 140 units 60 units 180 units 380 units @ $ 840 300 810 $ 1,950 Units sold at Retail 100 units 80 units 180 units @ $15 @ $15 1. Complete the table to determine the cost assigned to ending inventory and cost of goods sold using specific identification. 2. Determine the cost assigned to ending inventory and to cost of goods sold using weighted average. 3. Determine the cost assigned to ending inventory and to cost of goods sold using FIFO. 4. Determine the cost assigned to ending inventory and to cost of goods sold using LIFO.
