Tabletop Ranches, Inc. is considering the purchase of a new helicopter for $350,000. The firm's old helicopter has a book value of $85,000, but can only be sold for $60,000. It was being depreciated at the rate of $13,500 per year for four more years under an old depreciation method. The new helicopter will be depreciated using the 5-year MACRS schedule.
