Step-by-step explanation:
The total value of the ice cream shop owner's business assets can't be determined based on the given information. The provided reference only mentions changes in assets of Singleton Bank, not an ice cream shop. To determine the total value of the ice cream shop owner's business assets, we would need a list of all the assets owned by the ice cream shop, such as equipment, inventory, property, and any other investments or resources.
