Answer:
1. Ending inventory = Beginning inventory + Production - Sales
= 300 units + 15,000 units - 12,700 units
= 2,600 units
2. Per unit Product Cost Using Variable Costing
$
Direct material 20
Direct labor 60
Variable overhead 12
Product cost 92
3. Value of ending inventory under variable costing
= 2,600 units x $92
= $239,200
Step-by-step explanation:
The units of ending inventory is calculated as beginning inventory plus production minus sales.
Per unit product cost is the aggregate of variable cost per unit. This includes direct material cost, direct labour cost and variable overhead.
Value of ending inventory is the product of units of ending inventory and per unit product cost.
