Kingston Company uses the dollar-value LIFO method of computing inventory. An external price index is used to convert ending inventory to base year. The company began operations on January 1, 2013, with an inventory of $245,000. Year-end inventories at year-end costs and cost indexes for its one inventory pool were as follows:

Year Ended Ending Inventory Cost Index
December 31 at Year-End Costs (Relative to Base Year)
2013 $ 316,440 1.08
2014 387,270 1.17
2015 372,780 1.14
2016 361,020 1.10

For year 2013, I got 296,840

For year 2014, I got 341,300

Can't figure out the rest, PLEASE SHOW ALL WORK. This is my third time asking this question and no one can seem to get it right.
