Using the Average cost flow assumption, the Ending Inventory would be $770,000.
Here the prices of all the goods will be an average value of their various prices.
The average price is therefore:
= Total cost of goods / Total number of units
= ((3,200 x 400) + (3,600 x 800) + (4,000 x 1,200) + (800 x 4,200)) / (400 + 800 + 1,200 + 800)
= 12,320,000/3,200
= $3,850
Ending inventory is therefore:
= (Goods purchased - Goods sold) x 3,850
= (3,200 - 3,000) x 3,850
= $770,000
