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.

Intercontinental, Incorporated, uses a perpetual inventory system. Consider the following information about its inventory: August 1, purchased 10 units for $910 or $91 per unit; August 3, purchased 15 units for $1,590 or $106 per unit; August 14, sold 20 units; August 17, purchased 20 units for $2,300 or $115 per unit; August 28, purchased 10 units for $1,190 or $119 per unit; August 30, sold 23 units. Using LIFO, the cost of goods sold for the sale of 23 units on August 30 is ____ and the inventory balance at August 30 is _____.
