1. Determine the amount Telnex would calculate internally for ending inventory and cost of goods sold using first-in, first-out (FIFO) under a perpetual inventory system. Beginning inventory under FIFO was 25,000 units with a cost of $12.70 each. 2. Determine the amount Telnex would report externally for ending inventory and cost of goods sold using last-in, first-out (LIFO) under a periodic inventory system. Beginning inventory under LIFO was 25,000 units with a cost of $12.20 each. 3. Determine the amount Telnex would report for its LIFO reserve at the end of the year. 4. Record the year-end adjusting entry for the LIFO reserve. The balance of the LIFO reserve at the beginning of the year was $12,500. Complete this question by entering your answers in the tabs below.
