Answer:
Cost per equivalent unit= $5.152 Â
Explanation:
Cost per equivalent unit = Total conversion cost / Total equivalent unit
Fully worked = 76,000 - 10,000 = 66,000 Â units
Fully worked represents units started and completed in the same period.
Equivalent units
Item                  Units                  Equivalent unit
Opening inventory    17,000     90% × 17,000 =    15,300
Fully worked         66,0000   100% × 66,000 =   66,000
Closing inventory      10,000    70% ×  10,000 =   7,000
Total equivalent units                            88,300
Note also at that the degree of completion for opening inventory is the simply the balance of work remaining to be done.
For example, for materials, 10% of work has been done on the opening inventory in the last period, hence the balance of 90% would be done this period
Cost per equivalent unit = Total conversion cost / Total equivalent unit
= $( 9,010 + 445,915)/ 88300 units  =  $5.152
Cost per equivalent unit= $5.152 Â Â Â Â Â Â
