Step-by-step explanation:
The subject of this question is Mathematics. The question is asking about the details of an interest payment, including the amount of interest, the amount paid before, and the amount paid in the current period. To answer the question, we can refer to the given table, which shows the interest, pre-paid amount, and current period payment for different loan amounts.
In the table, we can see that for a loan amount of $9,000, the pre-paid amount is $2,700 and the current period payment is $6,300. This means that the total interest on the loan is $9,000 - $2,700 - $6,300 = $900.
