Final answer:
To calculate the value of the ending inventory based on FIFO, multiply the units of each purchase by their respective cost and sum them up. The correct answer is $540.00.
Step-by-step explanation:
To calculate the value of the ending inventory based on FIFO (First-In, First-Out), we need to determine the cost of the units purchased in chronological order. According to the given information, the units were purchased as follows:
- January 1: 10 units at $8.00 per unit
- January 18: 50 units at $9.00 per unit
- February 20: 20 units at $11.00 per unit
- March 15: 10 units at $12.00 per unit
Based on the FIFO method, the cost of the ending inventory is calculated by multiplying the units of each purchase by their respective cost and summing them up:
Cost of ending inventory = (10 units x $12.00) + (10 units x $11.00) + (20 units x $11.00) + (10 units x $9.00) = $120.00 + $110.00 + $220.00 + $90.00 = $540.00
Therefore, the correct answer is $540.00 (option e) for the value of the ending inventory based on FIFO.
