Final answer:
The weighted-average unit cost is $6 per unit, calculated by dividing the total cost of inventory purchased ($3600) by the total units purchased (600). The cost of the ending inventory under the average-cost method for 200 units on hand is $1200.
Step-by-step explanation:
To determine the weighted-average unit cost of inventory, we first calculate the total cost of all units purchased:
- 100 units at $5 each = $500
- 400 units at $6 each = $2400
- 100 units at $7 each = $700
- Total cost of purchases = $500 + $2400 + $700 = $3600
- Total units purchased = 100 + 400 + 100 = 600 units
We calculate the weighted-average unit cost by dividing the total cost by the total units purchased:
Weighted-average unit cost = Total cost / Total units = $3600 / 600 units = $6 per unit
To calculate the cost of the ending inventory under the average-cost method, we multiply the ending inventory units by the weighted-average unit cost:
Cost of ending inventory = 200 units * $6 per unit = $1200
The cost of the ending inventory using the average-cost method is $1200.
