Answer:
Absorption costing
Full cost per unit = $36
Variable costing
marginal cost = $32
Step-by-step explanation:
Absorption costing
Absorption costing values inventories and units produced using full cost per unit.
Full cost per unit
= Direct material cost + Direct labour + variable overheads + Fixed prod overhead
Fixed overhead per unit
= 90,000/22,500
= $4 per unit
Full cost per unit = 11 + 19 +2 + 4 =$36
Variable costing method
Variable (marginal) costing methods values inventories and units produced using variable cost per unit i.e marginal cost
Marginal cost = Direct material cost + Direct labour + variable overheads
Cost per unit = 11 + 19 +2 =$32
