Final answer:
The company's trade receivables consist of the sum of accounts receivable and notes receivable from customers, which in this case amounts to $16,500.
Step-by-step explanation:
The company's trade receivables can be calculated by summing up the accounts receivable and notes receivable from customers. In this case, the accounts receivable is $13,000 and the notes receivable from customers is $3,500, so the trade receivables would be $13,000 + $3,500 = $16,500.
