8. Write and run a SELECT statement that returns four columns from the Invoices table named Number, Total, Credits, and Balance Due. These columns should include this data: Number The invoice_number column Total The invoice_total column Credits Sum of the payment_total and credit_total columns Balance Due Invoice_total minus the sum of payment_total and credit_total Next, filter for invoices with a balance due thats greater than or equal to $500. Then, sort the result set by balance due in descending sequence. Last, use the ROWNUM pseudo column so the result set contains only the rows with the 10 largest balance dues.
