Step-by-step explanation:
1. Journal Entry to Record Normal Spoilage with $1,000 Residual Value:
Spoilage Expense $1,000
Accumulated Spoilage $1,000
Explanation: The spoilage expense is debited to record the cost of the rejected chairs, and the accumulated spoilage account is credited to accumulate the cost of spoilage.
2. Journal Entry to Record Normal Spoilage with Predetermined Overhead Rate:
Spoilage Expense $9,000
Factory Overhead Applied $9,000
Explanation: The spoilage expense is debited to record the cost of the spoiled chairs, which includes the predetermined overhead rate applied to each chair. The factory overhead applied account is credited to remove the applied overhead from the overall cost.
3. Revised Unit Cost after Fixed Spoilage Cost:
To calculate the revised unit cost, we need to consider the fixed spoilage cost and the number of good units.
Total cost for 10,000 chairs:
Total cost = Cost per chair × Number of chairs
Total cost = $22 × 10,000 = $220,000
Deduct the cost of spoiled chairs:
Spoiled chairs cost = Cost per chair × Number of spoiled chairs
Spoiled chairs cost = $22 × 1,000 = $22,000
Deduct the cost of fixed spoilage (paid to another firm):
Fixed spoilage cost = Cost per chair × Number of fixed spoilage chairs
Fixed spoilage cost = $15 × 1,000 = $15,000
Revised unit cost:
Revised unit cost = (Total cost - Spoiled chairs cost - Fixed spoilage cost) ÷ (Number of good chairs)
Revised unit cost = ($220,000 - $22,000 - $15,000) ÷ (10,000 - 1,000)
Revised unit cost = $183,000 ÷ 9,000
Revised unit cost = $20.33 (rounded)
Therefore, the revised unit cost after accounting for the fixed spoilage cost is $20.33.
