Periodic inventory systems allocate the cost of goods available for sale between cost of goods sold and ending inventory at the end of a period. Specific identification and FIFO give identical results whether the periodic or perpetual system is used. LIFO assigns costs to cost of goods sold assuming the last units purchased for the period are the first units sold. The weighted average cost per unit is computed by dividing the total cost of beginning inventory and net purchases for the period by the total number of units available. Then, it multiplies cost per unit by the number of units sold to give cost of goods sold.

A company uses a periodic inventory system. On November 1, the company had 8 items of beginning inventory with a cost of $22 per unit. On November 2, the company purchased 10 units at $21 per unit. On November 6, the company purchased 5 units at $25 per unit. Then, on November 8, the company sold 18 units. Using LIFO, the cost of the 18 units sold is _____.
