Prepare a UML class diagram $($classes$,$ associations, attributes, and multiplicities$)$ for the specified component of CADBURY Enterprises.

CADBURY sells its chocolates to customers through a network of company salespeople. Each type of chocolate is bought from a particular vendor and is given an initial list price. Each salesperson services a separate group of customers and is allowed to offer them various discounts from list to induce sales. Each sale can include one or more types of chocolates and can be paid for in any one of three ways: $(1)$ immediately in cash, $(2)$ on the $15$th of the following month, or $(3)$ over the course of six months. When cash is received, a cashier deposits it into a company bank account. Sales are signaled by invoices; cash receipts by remittance advices.

The policies above plus the information elements listed below are relevant to potential users of this data model, and they all should be included in its final structure $($attributes with asterisks are hints for some $($not all$)$ of the needed relationships$).$
