Answer: c. $2.89 per unit
Step-by-step explanation:
Using the First-In, First-Out method, we need to find the equivalent units first:
= Equivalent opening units + Units started and completed + Equivalent ending units
= (Opening units left to be completed) + (Units completed - opening units) + (proportion of closing units completed with respect to conversion)
= (3,000 * (1 - 40%)) + (12,000 - 3,000) + (1,000 * 40%)
= 11,200 units
Conversion costs = 32,363
Conversion cost per units:
= 32,363 / 11,200 units
= $2.89 per unit
