The Lansing Community College registrar's office is considering replacing some Canon copiers with faster copiers purchased from Kodak.

The office's 4 Canon machines are expected to last 5 more years. They can each be sold immediately for $1,300; their resale value in 5 years will be zero. The Canon machines require 4 operators; they are each paid $8.30 an hour and work 39 hours a week and 52 weeks a year. The machines break down periodically, resulting in annual repair costs of $1,260 for each machine. The cost of supplies for each machine will be $960 a year.

The total cost of the new Kodak equipment will be $111,000. The equipment will have a life of 5 years and a total disposal value at that time of $2,300. The Kodak system will require only 3 regular operators, working the same number of hours and earning the same wages. Kodak has offered the college a maintenance contract that covers all machine breakdowns; the cost of the contract is $960 per year. The cost of supplies for all the machines combined will be $3,120 a year.

Required Assuming a discount rate of 14%, compute the difference between the net present value if the registrar's office keeps the Canon copiers and the net present value if it buys the Kodak copiers. [Note: If your results favor keeping the Canon copiers, enter your net present value difference as a positive number; if your results favor buying the Kodak copiers, enter your net present value difference as a negative number.]
