On October 29, 2010, Lue Co. began operations by purchasing razors for resale. Lue uses the perpetual inventory method. The razors have a 90-day warranty that requires the company to replace any nonworking razor. When a razor is returned, the company discards it and mails a new one from Merchandise Inventory to the customer. The company's cost per new razor is $14 and its retail selling price is $80 in both 2010 and 2011. The manufacturer has advised the company to expect warranty costs to equal 6% of dollar sales. The following transactions and events occurred.
