Answer:
1.Total Equivalent Units   Materials   104,000 Conversion    98000
<u>2.</u> Cost per Equivalent Unit   Materials $ 1.5 Conversion $ 1
3. Materials Cost Ending Work in Process 13,500
4. Cost Of Units Transferred Out = $237,500
5. Both calculated and cost accounted are same. Mat. $ 156,000 Conversion $ 98000
Explanation:
The complete data is as follows:
 Production data: 
Pounds in process, May 1; materials 100% complete; conversion 80% complete 10,000 
Pounds started into production during May 100,000 
Pounds completed and transferred out ?
Pounds in Process 31 May : Materials 60 % , Conversion 20 % complete  15000
Cost Data
Work In Process May 1
Materials cost $ 1500
Conversion Cost $ 72 00
Cost Added During May 
Materials cost $ 154,500
Conversion Cost $ 90,800

Weighted-Average Method 
1. Equivalent Units
Particulars              Units       % of Completion       Equivalent Units
                                         Materials Conversion   Materials Conversion
Transferred Out    95000     100         100             95000      95000
<u>Ending WIP           15000        60          20                9000       3000   </u>
<u>Total Equivalent Units                                              104,000     98000</u>
<u />
Transferred Out units are calculated by adding Opening Inventory and production started and subtracting ending inventory units.
Transferred Out units = Opening Inventory+ production started -ending inventory units
Transferred Out units =10,000 + 100,00 - 15000= 95000 units.
2. Cost Per Equivalent Units
                                                        Materials         Conversion
Cost Of Opening Inventory         1500                  7200
<u>Cost Added                                  154500              90800</u>
<u>Total Costs                                   156000             98000</u>
Equivalent Units                          104000              98000
 Cost per Equivalent Unit            156000/104000        98000/98000
                                                        $ 1.5                           $1.0 
3. Cost of Ending Work In Process  $ 16500
Materials = 9000 * $ 1.5= $ 13500
Conversion = 3000 * $ 1.0=  $3000
We multiply the equivalenr number of units with the cost per unit to find the cost.
4. Cost Of Units Transferred Out = $237,500
Materials == 95 000 * $ 1.5= $ 142,500
Conversion = 95000 * $ 1.0=  $ 95000
5. A Cost Reconciliation Report
                                         Materials              Conversion
Ending WIP                       13500                   3000
<u>Transferred Out                 142500                95000</u>
<u>Total                                 156000                   98000</u>
These calculated costs reconcile with the costs given in the above data.
                                                       Materials         Conversion
Cost Of Opening Inventory         1500                  7200
<u>Cost Added                                  154500              90800</u>
<u>Total Costs                                   156000             98000</u>
