6. Mary wants to borrow $100,000 for the next ten years. She has the following two loan options: (TB) Triple Bank offers a 10 year sinking fund loan. Under the sinking fund loan, Mary will pay the interest at the end of each year on the loan. Additionally, Mary will make a (level) deposit into a sinking fund at the end of each year.
