When Albertina opened her law office, she bought $15,000 worth of law books and $6,800 worth of furniture. She paid $1,300 down and agreed to amortize the balance with semiannual payments for 5 years at 11% compounded semiannually. Find the amount of each payment. Then use the formula for the remaining balance to find the number of remaining payments when the loan has been reduced below $10,000. What is the amount of each payment? Round to the nearest cent as needed.)
