Explanation:

Ultra Co.'s inventory for January:

Date               Number of units   Unit balance      Unit cost     Total cost   

January 1             20,000                20,000               $13         $260,000       

January 20          30,000                50,000               $15         $710,000          

January 23          40,000                90,000               $17        $1,390,000      

January 31          (50,000)                                       ($16.60)    ($830,000)

Ending inventory                             40,000                              $560,000

Using the last-in, first-out (LIFO) method, the COGS = (40,000 units x $17 per unit) + (10,000 units x $15 per unit) = $680,000 + $150,000 = $830,000
