As part of expanding business to serve existing and potential Cattle farm clients and improving delivery services, management has been considering replacing its trucks with a newer, more fuel-efficient fleet for some time. The company has approached a local truck dealer and has got a deal to purchase 10 trucks for 125,000 each. Each new truck would be depreciated towards a salvage value of $50,000 over five years. Upon purchasing the new trucks, the company will sell its existing 10 used trucks to the dealer for their book value of $350,000. The existing fleet will be fully depreciated in one more year but is expected to be serviceable for five more years, at which time the vehicles would be worth only $5000 per unit as scrap. The new fleet is much more fuel-efficient and will require only $250,000 per year in fuel costs compared with $350,000 for the existing old fleet. In addition, the new fleet will require lower maintenance costs over the next five years, equal to an estimated $ 150,000 per year compared with the almost $400,000 currently being spent to keep the older fleet running. Assume a tax rate of 30%
