Bought a delivery truck and agreed to pay $60,600 at the end of three years. Rented an office building and was given the option of paying $10,600 at the end of each of the next three years or paying $28,600 immediately. Established a savings account by depositing a single amount that will increase to $91,200 at the end of seven years. Decided to deposit a single sum in the bank that will provide 10 equal annual year-end payments of $40,600 to a retired employee (payments starting December 31 of this year).
