Final answer:
The annual financial advantage for Lewelling Corporation as a result of accepting the special order is calculated by subtracting additional variable costs and the mold costs from the additional revenue generated by the special order. The result is a financial advantage of $39,390 (option a).
Step-by-step explanation:
To calculate the annual financial advantage or disadvantage of accepting the special order for Lewelling Corporation, we need to consider the additional revenue generated by the order and the additional variable costs, as well as the one-time cost of the special molds. The normal unit product cost is not entirely relevant because fixed costs will not change with the special order.
First, we calculate the additional revenue:
- 2,100 units x $39/unit = $81,900 total revenue
Then we calculate the additional variable costs per unit, which include the normal variable costs plus the added $2.00 per unit for modifications:
- Direct materials: $4.50
- Direct labor: $5.00
- Variable manufacturing overhead: $1.60
- Additional modifications cost: $2.00
- Total additional variable cost per unit = $13.10
Multiply the total additional variable cost per unit by the number of units:
- 2,100 units x $13.10/unit = $27,510 total variable costs
Subtract the total variable costs and the cost of the special molds from the total revenue to get the financial advantage (or disadvantage):
- $81,900 (revenue) - $27,510 (variable costs) - $15,000 (mold costs) = $39,390 financial advantage
The correct answer is a. $39,390.
