Final answer:
To calculate the ending inventory, subtract the units sold from the total units available for sale.
Step-by-step explanation:
To calculate the ending inventory, we need to track the beginning inventory, purchases, and sales. Let's start by calculating the total units available for sale:
- Beginning inventory: 300 units
- Purchases: 375 units
Total units available for sale: 300 + 375 = 675 units
Next, we need to subtract the units sold from the total units available for sale:
- Sales: 175 units on October 13 and 280 units on October 29
Total units sold: 175 + 280 = 455 units
Finally, we can calculate the ending inventory by subtracting the units sold from the total units available for sale:
Ending inventory = Total units available for sale - Total units sold = 675 - 455 = 220 units
