Final answer:
The cost of goods sold is $85,000.
Step-by-step explanation:
In this question, we are given the beginning inventory, inventory purchased during the year, inventory on hand at year-end, and cost of goods sold. To calculate the cost of goods sold, we can use the formula:
Cost of Goods Sold = Beginning Inventory + Purchases - Ending Inventory
Substituting the given values, we have:
Cost of Goods Sold = $50,000 + $75,000 - $40,000 = $85,000
Therefore, the correct answer is (a) $85,000.
