You can purchase an appliance (refrigerator, furnaces, A/C, etc.) maintenance contract. You can pay $1,000 today for a year's maintenance coverage or pay $90 per month, each month, starting today, for 12 months. If your investments earn 5.00% APR (compounded monthly), how much would you save or would it cost you (in present value terms) to pay on a monthly basis?
