Answer:
$260,000
Explanation:
Ending Balance of Supplies = $66,000
Beginning balance of Supplies = $66,000 - $10,000 = $56,000
Ending Balance of Supplies = Beginning balance of Supplies + Purchases for the period - Expense in the period
$66,000 = $56,00 + $270,00 - Expense in the period
Expense in the period = $260,000
The adjusting entry to supplies expense was $260,000.
