Oscar Industries has the following inventory information. $\begin{array}{rll}\text{ July }1& \text{ Beginning Inventory }& 40\text{ units at }\$110\\ 5& \text{ Purchases }& 240\text{ units at }\$112\\ 14& \text{ Sale }& 160\text{ units }\\ 21& \text{ Purchases }& 120\text{ units at }\$115\\ 30& \text{ Sale }& 150\text{ units }\end{array}$
Assuming that a periodic inventory system is used what is the amount allocated to ending inventory on a FIFO basis?

A) $10350
B) $10000
C) $35080
D) $34730

Under the FIFO (First-In, First-Out) method, the oldest inventory costs are assigned to the cost of goods sold first, leaving the newest inventory costs to remain in ending inventory. Here's the calculation:1. Beginning Inventory: 40 units at $110 = $4,4002. Purchases on July 5: 240 units at $112 = $26,8803. Purchases on July 21: 120 units at $115 = $13,8004. Total units available for sale = 40 + 240 + 120 = 400 units5. Total cost of units available for sale = $4,400 + $26,880 + $13,800 = $45,0806. Sales: 160 units + 150 units = 310 units sold7. Ending inventory units = 400 units - 310 units = 90 unitsUnder FIFO, the ending inventory would consist of:- All 120 units purchased on July 21 at $115 = $13,800- 90 units - 120 units = 0 units from July 21 purchase- Remaining 90 units from the July 5 purchase at $112 = 90 units * $112 = $10,080Total ending inventory value = $13,800 (from July 21 purchase) + $10,080 (from July 5 purchase) = $23,880However, given the options provided and the calculation mistake in the final step, the correct calculation for ending inventory under FIFO should be as follows:- The last 90 units would indeed come from the July 5 purchase: 90 units * $112 = $10,080Thus, the correct calculation for the ending inventory should consider the units and their respective costs correctly. Given the options and the mistake in the final step of calculation, the correct approach to find the ending inventory value under FIFO would involve correctly identifying and summing the costs of the most recently purchased units that remain in inventory after accounting for sales. The provided answer and calculation seem to have an error in the final computation or in matching the answer choices provided.
