Answer:
1,376,000 Â and 1.027
Explanation:
According to the scenario, computation of the given data are as follows:-
Price Index = Current Year Cost ÷ Base Year Cost
Year  Current Year Inventory Cost Divided Base Year Inventory Cost Price Index
January 1,2017 $1,000,000 ÷ $1,000,000 1
December 31,2017 $1,419,000 ÷ $1,290,000 1.1
December 31,2018 $1,527,600 ÷ $1,340,000 1.14
 Â
Ending Inventory At LIFO Cost = Layer at Base Price Year Inventory × Price Index
Dollar Value LIFO
Year  Layer At Base Price Year Inventory($) Multiple   Price Index Ending Inventory at LIFO Cost($)
2017 Â Â
January 1,2017 1,000,000 ×  1 1,000,000
December 31,2017 290,000  × 1.1      319,000
Total         1,290,000  1,319,000
2018 Â Â
January 1,2017 1,000,000 × 1 1,000,000
December 31,2017 290,000     × 1.1 319,000
December 31,2018 50,000     ×  1.14 57,000
            1,340,000  1,376,000
Dollar Value LIFO Inventory         =  $1,376,000
Internal Price Index = Ending Inventory at LIFO Cost ÷ Layer at Base Year Price
= 1,376,000 ÷ 1,340,000
= 1.027
We simply used the above formulas
