Answer:
(a) the cost of the goods sold for the September 30 sale and
(b) the inventory on September 30.
Explanation:
date transaction units unit price total
1 beginning inv. 23 $16 $368
5 sale -13 ($208)
17 purchase 24 $17 $408
30 sale -25 ($415)
30 ending inv. 9 $17 $153
When we use first in, first out (FIFO) inventory method, the price of the units sold are calculated using the oldest units in inventory.
The COGS of the units sold on Sept. 5 = 13 units x $16 = $208
The COGS of the units sold on Sept. 30 = (10 units x $16) + (15 units x $17) = $160 + $255 = $415
Ending inventory = 9 units at $17 = $153
