Carey Company owns a plot of land on which buried toxic wastes have been discovered. Since it will require several years and a considerable sum of money before the property is fully detoxified and capable of generating revenues, Carey wishes to sell the land now. It has located two potenital buyers. Buyer A, who is willing to pay $480,000 for the land now, or Buyer B, who is willing to make 20 annual payments of $75,000 each, with the first payment to be made 5 years from today. Assuming that the appropriate rate of interest is 9%, whom should Carey sell the land. Show calculations.
