Answer:
$262,900
Step-by-step explanation:
Net purchases = Purchases - Purchase return and allowances
Net purchases = 269500 - 14500
Net purchases = $255000
Cost of goods available for sale = Beginning Inventory + Net Purchases
Cost of goods available for sale = 45300 + 255000
Cost of goods available for sale = $300300
Cost of Goods sold = Cost of goods available for sale - Ending inventory
Cost of Goods sold = 300300 - 37400
Cost of Goods sold = $262,900
So, Coronado's cost of goods sold under a periodic inventory system is $262,900.
