Final Answer:
The costs assigned to ending inventory using specific identification are calculated as follows: For the 8 units sold from the December 7 purchase, the cost assigned to the ending inventory is $104 (8 units × $13). For the 7 units sold from the December 14 purchase, the cost assigned to the ending inventory is $133 (7 units × $19). The total cost assigned to the ending inventory from these specific identification sales is $237.
Step-by-step explanation:
In specific identification inventory costing, the costs assigned to ending inventory are determined by directly attributing the specific costs of the units sold. In this scenario, 8 units out of the 15 units sold originate from the December 7 purchase at a cost of $13 per unit. The cost assigned to the ending inventory for these 8 units is $104 (8 units × $13).
Additionally, 7 units of the total 15 units sold are from the December 14 purchase, priced at $19 per unit. The cost allocated to the ending inventory for these 7 units is $133 (7 units × $19).
When summing up the costs assigned to ending inventory based on specific identification for both purchases ($104 from December 7 purchase and $133 from December 14 purchase), the total cost assigned to the ending inventory amounts to $237. This represents the specific costs attributed to the units remaining in inventory after the sale based on the specific identification of the units sold from each purchase.
