Compute the ending inventory at September 30 using the FIFO, LIFO and average-cost methods.

FIFO = $4,128

LIFO = $4,026

weighted average-cost = $ 4,078.08

Explanation:

FIFO

Inventory : 12 units × $114 = $1,368

                  24 units × $115 = $2,760

Total                                    = $4,128

LIFO

Inventory : 14 units × $110 = $1,540

                  22 units × $113 = $2,486

Total                                    = $4,026

Weighted Average Cost

New Cost per Unit = Total Cost / Total Units

September 12

New Cost per Unit = ((14 units × $110 ) + (45 units × $113)) / (14 units + 45units)

                               = $112.59

September 19

New Cost per Unit = ((59 units × $112.59 ) + (57 units × $114)) / (59 units + 57units)

                               = $113.28

September 19

New Cost per Unit = ((116 units × $113.28 ) + (24 units × $115)) / (116 units + 24 units)

                               = $113.57

Inventory Cost = (140-104) units × $113.28

                        = $ 4,078.08

the answer is a. $209,000
