Answer:
variable costs per unit = $10.57
variable cost per unit for utilities = $0.85
variable cost per unit for maintenance = $0.25
Step-by-step explanation:
I believe that the question is incomplete: the missing part is that both utilities and maintenance costs are mixed.
Production in units 3,900
Variable production cost s:
Direct materials $9,675 / 3,900 = $2.4808 per unit
Direct labor $27,420 / 3,900 = $6.9846 per unit
Utilities ($3,702 - $387) / 3,900 = $0.85 per unit
Maintenance ($1,233 - $258) / 3,900 = $0.25 per unit
total variable costs per unit = $10.5654 ≈ $10.57
