Natasha needs special equipment for her job as a builder. She has two options. She can buy the equipment which costs $12 800. Natasha will finance this purchase through the vendor by making regular monthly payments over 6 years at an interest rate of 7.3%, compounded monthly. At the end of the 6 years, the equipment will be worthless. She can also lease the equipment at a cost of $185 per month. Both options require a down payment of $1980.
