Park uses a perpetual inventory system. 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 per unit costs to
three decimals, but inventory balances to the dollar.) For specific identification, ending inventory consists of
225 units, where 90 are from the March 30 purchase, 80 are from the March 20 purchase, and 55 are from
beginning inventory.
