Final answer:
To calculate the cost of goods sold using the weighted average method, determine the weighted average unit cost of the switch plates in stock and multiply it by the number of switch plates sold.
Step-by-step explanation:
To calculate the cost of goods sold using the weighted average method, we need to determine the weighted average unit cost of the switch plates in stock.
Here's how to calculate the weighted average unit cost:
- Start with the units in stock at the beginning of the year and their respective costs: 150 units at $4.00 each.
- Add the units purchased during the year and their respective costs: 200 units at $4.20 each, 200 units at $4.40 each, and 250 units at $4.80 each.
- Divide the total cost by the total number of units: (150 * $4.00) + (200 * $4.20) + (200 * $4.40) + (250 * $4.80) divided by (150 + 200 + 200 + 250).
- The weighted average unit cost is $4.47.
To calculate the cost of goods sold, multiply the weighted average unit cost by the number of switch plates sold: $4.47 * 570 = $2,546.90.
