Del Bosque Co. began using dollar-value LIFO for costing its inventory two years ago. The ending inventory for the past two years in end-of-year dollars was $100,000 and $150,000 and the year-end price indices were 1.0 and 1.2, respectively. Assuming the current inventory at end of year prices equals $215,000 and the index for the current year is 1.25, what is the ending inventory using dollar-value LIFO?

$177,500.

$186,400.

$190,000.

$188,750.
