Answer:
Results are below.
Step-by-step explanation:
Giving the following information:
Purchase 1 (earliest) for $20
Purchase 2 (middle) for $15
Purchase 3 (latest) for $25
The FIFO (first-in, first-out) method, allocates costs to the cost of goods sold using the purchase price of the firsts units incorporated into inventory. On the contrary, the ending inventory cost is calculated with the costs of the lasts units incorporated.
Assume that the company sells the number of units equivalent to the first lot. Then, the cost of goods sold will be $20; and the ending inventory $40 (15+25).
