Using first-in, first-out (FIFO), the Cost of Goods Sold equals $30.
FIFO is an inventory method that assumes that items that are in store are the first to be sold by the business, while those items that are recently purchased or manufactured will be sold later.
With the FIFO method, the cost of goods sold is based on past costs while the ending inventory costs are based on the most recent costs.
Beginning inventory of 4 items at $10 each = $40 ($10 x 4)
Purchases of 3 items at $11 = $33
Sales = 3 items
Using first-in, first-out (FIFO), the Cost of Goods Sold equals $30 ($10 x 3).
Thus, under FIFO, the Cost of Goods Sold equals $30.
