Since the multiplicities next to Cash Accounts class are 1..1, it means that every Cash Account instance can be associated with only one Cash Disbursement instance, and since the multiplicities next to the Cash Disbursements class are 0..*, it means that a Cash Disbursement instance can be associated with zero or multiple Cash Account instances. 
Therefore, the best way to implement this association would be to post the primary key of Cash Accounts as a foreign key in Cash Disbursements table. This is because Cash Accounts has a unique identifier (primary key), and every Cash Disbursement entry can be associated with only one Cash Account instance. Therefore, the foreign key in Cash Disbursements can point to the primary key of the Cash Accounts table.
