Final answer:
The budgeted cost of goods sold for October is calculated by adding the beginning inventory to the purchases and then subtracting the ending inventory, resulting in $9,700.
Step-by-step explanation:
To calculate the budgeted cost of goods sold for October, we would start by adding the initial inventory to the purchases and then subtracting the ending inventory:
Beginning inventory: $2,300
+ Purchases: $8,700
- Ending inventory: $1,300
= Budgeted Cost of Goods Sold: $9,700
The budgeted cost of goods sold for the store in October would thus be $9,700.
