Marshall Mathers goes to the bank to get a loan. The bank says that if he wants a loan of $10,147, he will have to pay back $11,147 after 14 months. Marshall renegotiates the loan at the same interest rate so that he borrows the $10,147, repays $5,000 after 11 months and repays the balance five months later (16 months after taking out the loan). What is his second (final) repayment?
