Answer:
b. $612,000
Step-by-step explanation:
Dec 31, 2013 inventory = $660,000
Value of Dec 31, 2013 inventory at base year (2012) prices = $660,000/110*100 = $600,000
The real-dollar quantity increase in inventory = ($600,000 - $480,000) = $120,000
Value of this real dollar quantity increase in inventory at Dec 31, 2013 prices= $120,000 * 110/100 = $132,000 (LIFO layer to the Dec 31, 2012 inventory)
Value of Dec 31, 2013 inventory = Dec 31, 2012 inventory + The value of LIFO layer formed
Value of Dec 31, 2013 inventory = $480,000 + $132,000
Value of Dec 31, 2013 inventory = $612,000
