Tommy Systems has chosen to move forward with making and selling the wireless headphones that it developed . The company needs to buy tools to make the microphone for the headphones before it can start this project. Due to the mic's need to be sensitive and its small size, the company needs to use special tools to make it. Bale Tower, who is the head of the company, has found a place to buy the tools. Obrey Acoustical Equipment has offered to sell the needed equipment to Tommy Systems for $6 million. The straight-line method will be used to figure out how much the tools are worth. At the end of four years, the tools should be worth nothing on the market. Tommy Systems can get the money for the purchasing by selling bonds with a yield of 12%. The company can also get the tools from Maze Leasing on a lease. The lease says that four payments of $1.4 million are due at the start of every year. If the company tax rate is 21%, should Tommy buy the equipment or rent it?
