Answer:
The cost of the work transferred-out during May is $21,600
Explanation:
Cranford Company completed and transferred out 3,000 units in May 2016. There were 100 units in the Work-in-Process Inventory on May 31, 2016, 40% complete as to conversion costs, 100% complete as to materials.
Material costs per unit = $9,920/3,100 = 3.2
Conversion costs of work transferred-out = $12,160/(3,000 + 100x40%)x3,000 = $12,000
The cost of the work transferred-out during May = Material costs + Conversion costs = $3.2 x 3,000 + $12,000 = $21,600
