Answer and Explanation:
The computation of the ending inventory by following methods are
a. Under FiFO
= 14 units at $39
= $546
b. Under LIFO
= 14 units at $29
= $406
c, Under average cost method
But before that the average cost per unit should be determined
= (22 units at $29 + 31 units at $20 + 46 units at $39) ÷ (22 units + 31 units + 46 units)
= ($638 + $620 + $1,794) ÷ (99 units)
= $30.83
Now the ending inventory is
= $30.83 × 14 units
= $431.62
= $432
