Answer:
a. An additional layer of $12,760 is added to the 12/31/2021 balance.
Step-by-step explanation:
The computation of the inventory balance is given below:
2021 Base year cost is
= $131,040 ÷ 1.05
= $124,800
Additional layer is
= $124,800 - $101,600
= $23,200
2022 Base year cost is
= $150,040 ÷ 1.10
= $136,400
Additional layer is
= ($136,400 - $124,800 ) × 1.10
= $11,600 1.10
= $12,760
Therefore the first option is correct
