Total fixed assets are $4,100,000 per year. Variable costs will be $215, and units will sell for $335 each. The company will need to purchase equipment for $15,000,000 which will be depreciated as a seven-year MACRS property. In five years, the equipment can be sold for $3,500,000. The company is in the 21 percent tax bracket and has a 14 percent required return on its projects. The company will use land that was purchased for $1,800,000 three years ago. The land could be sold today for $2,400,000 and it is believed that it will be sold in five years for $2,700,000.
