Explanation:

given data

Date of Purchase    UnitsUnits CostTotal Cost

Jan. 7                          4,000     $4.00        $16,000

Feb 16                          12,000      5.00          60,000

March 22                  16,000      6.00          96,000

Totals                           32,000                    $172,000

solution

we get here for the cost of goods sold and the ending inventory  that is

Date    Particulars     Units (1)Rate (2)Cost (1×2)

7-Jan     Purchase     4000          $4          $16,000

16-Feb     Purchase      12000  $5          $60,000

March 22    Purchase      16000  $6          $96,000

Total                              32,000           $172,000

Sold Units                      18,000                      0  

Ending Inventory              14,000  

Weighted average                                                   $5.38  

rate of purchase                        

($172,000/32,000)  

and

Method  

                                             FIFO (a)    LIFO (b)   Weighted Average (c )

Value of Ending Inventory    $84,000   $66,000$10,990

Cost of goods sold                $88,000    $106,000$161,010

(Total Cost - Ending Inventory)

and

gross profit ratio for the first quarter using FIFO, LIFO, and Average cost  is

Method

Particulars                        FIFO          LIFO       Weighted Average

Sales (18,000 x $9)      $162,000$162,000$162,000

Less: Cost of Goods Sold   -$88,000-$106,000-$161,010

Gross Profit                    $74,000   $56,000  $990

and

The weighted average method is show that least profit and  FIFO method is show you  highest profit in the all three method

3rd the reason why is because of management and leadership
