(5 pts) You have $25,000 to invest for an eight-year time period. You intend to invest the entire sum now and then withdraw the resulting amount eight years from now. Your two investment opportunities are as follows. The first will pay simple interest at the rate of 15% per year. The second will pay compound interest at the rate of 2.75% every three months. Calculate the interests of the two options. Which option is preferred? I +(5 pts) Apex Inc. just purchased a certain used machine for production. The machine will cost $2,000 to maintain in year 1. Maintenance costs will increase by $600 for each additional year the machine is kept (i.e., maintenance costs will be $2,600 in year 2, $3,200 in year 3, etc.). If the company can earn 10% interest on their investment, how much must they invest today to cover their maintenance costs for the machine for the next six years?
