Ending inventory at retail = $442,000
To Calculate ending inventory at cost using the dollar-value LIFO retail method
Ending inventory at cost = (Ending inventory at retail / Retail price index (ending)) * Retail price index (beginning)
Ending inventory at cost = ($442,000 / 1.10) * 1.00
Ending inventory at cost = $401,818.18
To Calculate cost of goods sold
Cost of goods sold = Beginning inventory cost + Net purchases cost - Ending inventory cost
Cost of goods sold = $300,000 + $521,400 - $401,818.18
Cost of goods sold = $420,581.82
Therefore, Lance-Hefner Specialty Shoppes' ending inventory at cost is $401,818.18, and their cost of goods sold is $420,581.82.
