The Riteway Ad Agency provides cars for its sales staff. In the past, the company has always purchased its cars from a dealer and then sold the cars after three years of use. The company's present fleet of cars is three years old and will be sold very shortly. To provide a replacement fleet, the company is considering two alternatives: At the end of three years, the fleet could be sold for one-half of the original purchase price. Lease alternative: The conpany can lease the cars under a three-year lease contract. The lease cost would be $67,800 per year (the first payment due at the end of year 1). As part of this lease cost, the omer would provide a11 servicing and repairs, license the cars, and pay a11 the taxes. Riteway would be required to make a $13,508 security deposit at the beginning of the lease period, which would be refunded when the cars were returned to the owner at the end of the lease contract.
