Answer:
The total amount of equivalent units for materials and conversion are 69.600 units and 62,400 units respectively.
Explanation:
(It is assume that both opening and ending inventory materials are 70% complete and the units are 30% complete with respect to conversion.)
Calculation of Material equivalent units
Closing units = 20,000 + 55,000 - 57,000 = 18,000
In weighted average period cost for material include both cost of opening stock material and cost of material incurred in the period.
Eq material = 20,000 + 55,000 - (18,000*30%) = 69,600units
(opening units losts it identity)
Calculation of Conversion Cost equivalent units
Eq conversion cost = 20,000 + 55,000 - (18000 *%70)
= 62,400 units
