Answer:
$129,800
Step-by-step explanation:
Calculation to determine the inventory at December 31, 2017,
Ending inventory at Dec 31, 2017 using dollar value LIFO = $100,000 + (120,000 - 100,000) * 1.05 + ($128,000 - $120,000) * 1.10
Ending inventory at Dec 31, 2017 using dollar value LIFO = $100,000 + $21,000+ $8,800
Ending inventory at Dec 31, 2017 using dollar value LIFO = $129,800
Therefore Under the dollar-value LIFO method the inventory at December 31, 2017, should be $129,800
