Final answer:
The cost of the ending inventory using the Perpetual FIFO inventory valuation method is $3,640.
Step-by-step explanation:
In order to determine the cost of the ending inventory using the Perpetual FIFO inventory valuation method, we need to calculate the cost of the units sold first. This method assumes that the first units purchased are the first ones sold.
For the purchases and sales given:
- January: 10 units at $120 each
- February: 20 units at $125 each
- May: 15 units at $130 each
- September: 12 units at $135 each
- November: 10 units at $140 each
Leading to the following cost of units sold:
- January: 6 units at $120 each = $720
- February: 5 units at $125 each = $625
- May: 9 units at $130 each = $1,170
- September: 8 units at $135 each = $1,080
- November: 13 units at $140 each = $1,820
The total cost of units sold is $5,415. Since there were 26 units remaining in ending inventory, the cost of the ending inventory is calculated as:
Cost of ending inventory = (Cost per unit x Number of units) = ($140 x 26) = $3,640
