Answer:
Explanation:
The computation for each month is shown below:
For January
Material cost units
= Material Transferred out units × completion percentage + Material ending work in progress units × completion percentage
= 38,700 × 100% +  12,200 × 100%
= 50,900 units
Conversion units
=  Conversion Transferred out units × completion percentage+ Conversion ending work in progress units × percentage given
= 38,700 × 100% +  12,200 × 44%
= 44,068 units
For March
Material cost units
= Material Transferred out units × completion percentage + Material ending work in progress units × completion percentage
= 43,400 × 100% +  9,000 × 100%
= 52,400 units
Conversion units
=  Conversion Transferred out units × completion percentage+ Conversion ending work in progress units × percentage given
= 43,400 × 100% +  9,000 × 73%
= 49,970 units
For July
Material cost units
= Material Transferred out units × completion percentage + Material ending work in progress units × completion percentage
= 50,600 × 100% +  19,700 × 100%
= 70,300 units
Conversion units
=  Conversion Transferred out units × completion percentage+ Conversion ending work in progress units × percentage given
= 50,600 × 100% +  19,700 × 21%
= 54,737 units
