Final answer:
The ATP quantity of 4 and the ATP of 3 days from today indicate that there are currently 4 units of the product in stock, and customers can expect delivery in 3 days from today.
Step-by-step explanation:
The ATP quantity of 4 and the ATP of 3 days from today indicate that there are currently 4 units of the product in stock. However, customers can expect delivery in 3 days, but this does not necessarily mean that only 4 units are available or that more may become available later. It simply means that customers can expect delivery in 3 days from today.
