What is the journal entry for the following question?

ABC uses a periodic inventory system, and the ending inventory for each year is determined by taking a complete
physical inventory at year-end. A physical count was taken on December 31, 2016, and the inventory on-hand at
that time totaled $70,000, which reflects historical cost. Record the adjusting entry for properly recognizing
2016 Cost of Goods Sold. Hint: This was the first year of operations, so beginning inventory balance is zero.
Additionally, ABC adheres to GAAP by recording ending inventory at the lower of cost and net realizable value at a total inventory level.
A review of inventory data further indicated that the current retail sales value of the ending inventory is $60,000 and estimated costs of
completion and shipping is 10% of retail. Be sure to make an additional adjustment, if necessary, to properly value ending inventory
using the Loss and Allowance methodology. For Income Statement presentation purposes, be sure to use the Loss Method for accounting
for adjustments of inventory to market value.
