Final answer:
To calculate the ending inventory using dollar-value LIFO, adjust the ending inventory for each year by its price index to reflect base year costs, and then sum the adjusted values. The ending inventory for Angle Company using dollar-value LIFO is $264,600.
Step-by-step explanation:
The student has asked for the calculation of ending inventory using dollar-value LIFO (Last-In, First-Out) method of inventory cost determination under varying price levels. To find the ending inventory using dollar-value LIFO, we must adjust the ending inventory amounts by the corresponding price indices to find the inventory at base year cost, then apply the LIFO cost layering.
First year base-layer inventory at end-of-year dollars: $180,000 / 1.0 (price index) = $180,000.
Second year inventory addition at base year cost: ($270,000 / 1.2) - $180,000 = $45,000.
Current year inventory addition at base year cost: ($387,000 / 1.25) = $309,600. LIFO layer increase: $309,600 - $270,000 / 1.2 = $39,600.
The ending inventory using dollar-value LIFO is the sum of the base layer and the increases due to inflation adjusted for each year: $180,000 (base layer first year) + $45,000 (second year adjustment) + $39,600 (current year adjustment) = $264,600.
