Closing inventory calculation requires opening inventory, assumed 0 for first year

Steps:

• Calculate net sales: $17,000 -$6,000 = $11,000.
• Calculate gross profit: 25% × $11,000 =$2,750.
• Calculate cost of goods sold: $11,000 -$2,750 = $8,250.
• Calculate closing inventory: purchases - cost of goods sold = $12,900 -$8,250 = $4,650 (not in options).

Not enough information: Calculated closing inventory ($4,650) does not match any choice; options may contain error.

Final answer: Not enough information.
