Answer:
the ending inventory and cost of goods sold for 2021 based on a periodic inventory system is $816,000 and $3,378,000 respectively
Explanation:
The computation is shown below
Cost of goods sold is
= (117,000 units - 114,000 units) × $24 + 114,000 units × $29
= 3,000 units × $24 + 114,000 units × $29
= $72,000 + $3,306,000
= $3,378,000
And, the ending inventory is
= (37,000 units - 3,000 units) × $24
= $816,000
Hence, the ending inventory and cost of goods sold for 2021 based on a periodic inventory system is $816,000 and $3,378,000 respectively
