Answer:
Cost per unit of conversion cos= $3.56 per unit
Step-by-step explanation:
Cost per unit of conversion cost = Total cost/ total equivalent unit
Item Units Equivalent unit
Opening inventory 92,000 75% ×92,000 = 69000
Fully worked 262,000 100% × 262,000 = 262000
Closing inventory 36,000 10%× 36,000 = 3600
Total equivalent unit 334,600
Cost per unit of conversion cost = Total cost/ total equivalent unit
= (91,700 + 1,100,620 )/ 334,600 units
= $3.56 per unit
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, 25% of work has been done on the opening inventory in the last period, hence the balance of 75% would be done this period
