Final answer:
The ending inventory balance at the end of the year according to the FIFO method is $1,475, calculated by summing up the value of the latest purchases until the 25 units on hand are accounted for. Therefore, the correct option is a. $1,475.
Step-by-step explanation:
The student's question pertains to calculating the ending inventory balance using the FIFO (First In, First Out) inventory valuation method. To determine the ending inventory according to FIFO, we would start by taking the latest purchases until we have accounted for the 25 units on hand at the end of the year:
- 15 units at $61 = $915
- 10 units from the second purchase at $56 = $560
This gives us a total ending inventory balance of 15 units at $61 plus 10 units at $56, which equals $915 + $560, totaling $1,475.
