Answer:
a. $75,000.
Explanation:
The computation of the estimated cost of missing inventory is as follows
But before that the cost of goods sold is
The cost of goods sold is
= $5,700,000 × 0.75
= $4,275,000
Now as we know that
Closing Inventory = opening inventory + Purchases - Cost of goods sold
= 900,000 + 4,500,000 - 4,275,000
= $1,125,000
But it reveals that the ending inventory is $1,050,000
So, the missing inventory is
= $1,125,000 - $1,050,000
= $75,000
