I understand how to get the estimated ending inventory at retail, but having a hard time figuring out the estimated ending inventory at cost and estimated cost of goods sold. Please help me to understand how to resolve this problem.

Smith-Kline Company maintains inventory records at selling prices as well as at cost. For 2018, the records indicate the following data:

($ in 000s)CostRetailBeginning inventory$60$100Purchases533935Freight-in on purchases26Purchase returns11Net markups3Net markdowns7Net sales812

Required:

Assuming the price level increased from 1 at January 1 to 1.80 at December 31, 2018, use the dollar-value LIFO retail method to approximate cost of ending inventory and cost of goods sold.(Do not round intermediate calculations. Round final answers to the nearest whole dollar. Enter your answers in thousands.)
