Final answer:
When a customer is 30 days past due, a company should follow its policies on late payments, which in this case involve charging a $10 late fee and a $5 daily fee thereafter.
Step-by-step explanation:
If a customer is 30 days past due, the appropriate steps would be specific to the company's policies on handling late payments. However, based on the information provided, the credit card company charges a $10 late fee as soon as a payment is overdue and an additional $5 daily late fee for each day the payment remains unpaid. Therefore, if a customer is 30 days past due, the company should implement late fees accordingly. It is important to adhere to the stated policies for late payments to ensure fairness and consistency.
