Answer:
a. FIFO - Inventory Used: $39900 Remaining Inventory: $14700
b. LIFO - Inventory Used: $41700 Remaining Inventory: $12900
c. Weighted Average Cost - Inventory Used: $40950 Remaining Inventory: $13650
Explanation:
Jan 01. Beginning inventory = 40 x $165 = $6600
Aug 13. Purchases 200 x $180 = $36000
Nov 30. Purchases 60 x $200 = $12000
Ending inventory = 75 units
Inventory Used = 300 – 75 = 225
(a) First-In-First-Out (FIFO)
This is the method where the inventory first received is the one that is used first. Common method when the inventory is perishable and would be wasted if left too long.
Inventory Used:
40 x $165 = $6600
185 x $180 = $33300
Total = $39900
Remaining Inventory:
15 x $180 = $2700
60 x $200 = $12000
Total = $14700
(b) Last-In-First-Out
Method whereby the inventory received latest is used first. Common in goods that are bulky. the inventory on top (latest purchased) is used first.
Inventory Used:
60 x $200 = $12000
165 x $180 = $29700
Total = $41700
Remaining Inventory:
40 x $165 = $6600
35 x $180 = $6300
Total = $12900
(c) Weighted Average Cost
This is whereby you divide the cost of goods sold by the number of units available for sale.
54,600 / 300 = $182
Inventory Used: 225 x $182 = $40950
Remaining inventory = 75 x $182 = $13650
Those are supply curves and demand curves. Supply curves have to meet the production requirements, while demand curves have to meet the consumer's willingness to pay.
