I think statement 3 may seem tricky because it feels like there should be more to it. But it just means it's a simple entity. I think the Sales Inventory should be an entity on its own. And for statement 4, there should be an entity named "Sales" which contains an attribute named "charge". There would be a one-to-one relationship between Sales Inventory and Sales. The Salesperson entity should have a one-to-many relationship with the Sales Inventory entity (crows feet on the Sales Inventory), since one sales person can have many sales. And the Salesperson entity should also have a one-to-many relationship with the Customers entity (crows feet on Customers), since a salesperson can have multiple customers.

This is my opinion on all this. I may be wrong though. Good luck.
