Answer:
the ending inventory using the FIFO cost flow assumption is $282,900
Step-by-step explanation:
The computation of the ending inventory using the FIFO cost flow assumption is shown below;
But before that first we have to determine the ending inventory units i.e.
= 280 + 380 + 480 + 290 - 1,200
= 230 units
So, the ending inventory is
= 230 units × $1,230
= $282,900
Hence, the ending inventory using the FIFO cost flow assumption is $282,900
