Show your understanding of the cost of goods sold model by filling in the missing numbers in the table. January February March Beginning inventory $192 $140 + Purchases 411 3 = Cost of goods available for sale $603 - Ending inventory 227 312 = Cost of goods sold $463 $493 To illustrate the different inventory cost flow assumptions, consider the following example of Russell Company, which purchased inventory at three different times at three different prices. Total Units Cost per May 1 Purchase May 15 Purchase May 20 Purchase 25 25 25 Unit $ 10 16 20 Cost $ 250 400 500 Goods available for sale 75 1,150 Russell purchased a total of 75 units, which cost a total of $1,150. On May 31st a customer purchased 25 units. Russell's selling price was $23 per unit. Under the FIFO method, what is the unit cost of the items sold first? Fill in the table below, calculate Russell Company's sales revenue, cost of goods sold, gross profit and ending inventory balance under each of the three inventory cost flow assumptions. When required, round your answers to the nearest dollar. However, do not round your intermediate calculations. FIFO Average Cost Revenue Cost of goods sold Gross profit Ending inventory
