Laker uses a periodic inventory system. For specific identification, ending inventory consists of 525 units, where 290 are from the January 30 purchase, 80 are from the January 20 purchase, and 155 are from beginning inventory. Determine the cost assigned to ending inventory and to cost of goods sold using (a) specific identification, (b) weighted average, (c) FIFO, and (d) LIFO.(Round your cost per unit to 3 decimal places.)
