The Lansing Community College registrar's office is considering replacing some Canon copiers with faster copiers purchased from Kodak.
The office's 5 Canon machines are expected to last 6 more years. They can each be sold immediately for $1,500; their resale value in 6 years will be zero. The total cost of the new Kodak equipment will be $113,000; the equipment will have a life of 6 years and a total disposal value at that time of $2,900.
The 5 Canon operators are paid $8.30 an hour each. They work a 40-hour week and 52 weeks a year. The machines break down periodically, resulting in annual repair costs of $1,020 for each machine. Supplies cost $960 a year for each Canon copier.
The Kodak system will require only 3 regular operators to do the same work. Kodak has offered the college a maintenance contract that covers all machine breakdowns; the cost of the contract is $1,200 per year. Total cost for all supplies will be $260 per month.
Required
Assuming a discount rate of 12%, 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.]
