Final answer:
When a salesperson receives cash as an earnest money deposit, they should put it into a trust account.
Step-by-step explanation:
When a salesperson receives cash instead of a check as an earnest money deposit, they should put it into a trust account. A trust account is a separate bank account that is used to hold money received from clients and other individuals. By placing the cash in a trust account, the salesperson ensures that it is securely held until the transaction is completed and the funds can be distributed according to the agreed-upon terms.
