Final answer:
The exact placement volume at which a reminder is sent for an EA placement volume close to 200 depends on the predefined threshold set by the system or company policy, which could be a percentage or a fixed amount below the target. Without this specific information, it's not possible to provide an exact volume for the reminder trigger.
Step-by-step explanation:
If a reminder is sent for an EA placement volume when it is close to 200, and we're looking to determine at what placement volume the reminder is triggered, additional context is needed as the specific threshold for sending the reminder could vary based on the system or the company's policy. In some systems, thresholds could be set at a percentage of the total, such as 90%, or at a fixed amount below the target, such as 10 units before reaching 200. However, without specific information about the predefined threshold set for sending reminders, it is not possible to provide an exact volume at which the reminder would be sent. Generally, companies set reminders at levels that allow sufficient time for necessary actions to be taken so that targets are met.
