$1,400$ units purchased during the year were returned to suppliers for credit. Jillet was also given credit for the freight charges of $$0\mathrm{.}50$ per unit on the original purchase. The units were defective and were returned two days after they were received. The remaining inventory was paid within the discount period. $($Hint: The discount applies only to inventory and not the freight.$)$

Sales for the year totaled $65,000$ units at $$18$ per unit. $($Hint: The cost of the inventory sold includes the purchase cost of those units plus freight less purchase discount.$)$

Determine ending inventory and cost of goods sold at the end of the year.

For financial reporting purposes, the company uses LIFO $($amounts based on a periodic inventory system$).$ Record the year$-$end adjusting entry for the LIFO reserve, assuming the balance in the LIFO reserve at the beginning of the year is $$15,800.$

Determine the amount the company would report as income before taxes for the year under LIFO. Operating expenses other than those indicated in the above transactions amounted to $$158,000.$
