Problem 5: Newnan Furniture owns and operates an industrial lift truck in its warehousing operation. The record indicates that the lift truck was purchased four years ago at $15,000. The estimated salvage value is $4,000 after four years of operation. First-year O&M expenses were $2,000, but the O&M expenses have increased by $400 each year for the first four years of operation. Using i = 10%, compute the annual equivalent costs of the lift truck for four years on a before-tax basis
