Answer and Explanation:
For materials
Equivalent completed units = Completed units + WIP ending
= 111,700 + 20,300
= 132,000 units
Cost of materials = Beginning WIP + Cost of materials added
= 22,300 + 370,000
= $392,300
Cost of material per units = 392,300 ÷ 132,000
= $2.97197
For conversions
Equivalent completed units = Completed units + WIP ending
= 111,700 + 20,300 × 30%
= 117,790 units
Cost of Conversion = Beginning WIP + Cost of conversion added
= 19,700 + 280,000
= $299,700
Cost of conversion per units = 299,700 ÷ 117,790
= $2.54436
Total cost of units completed and transferred out
= 111,700 × (2.97197 + 2.54436)
= $616,174
