Question

The Bowling Green State University 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 $900; their resale value in 5 years will be zero. The Canon machines require 4 operators; they are paid $8.40 an hour each and work 38 hours a week and 51 weeks a year. The machines break down periodically, resulting in annual repair costs of $960 for each machine. Supplies cost $1,200 a year for each machine. 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 $1,900. The Kodak system will require only 2 regular operators.  Kodak has offered the college a maintenance contract that covers all machine breakdowns; the cost of the contract is $1,020 per year. Total cost for all supplies will be $3,480 per year. 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. 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.

Answer 1

Particulars	Time	PVF @14%	Canon($)	Kotak($)
Initalcost of the Machine	0	1	-	$111,000
Dispoal Value of old machine ($900 * 4 )	0	1		-$3,600
Oprators Cost (4*$8.40*38*51*PVF) & (2*$8.40*38*51*PVF)	1-5	3.4331	$223,552	$111,776
Annual repair cost(960*4*pvf)&(1020*PVF)	1-5	3.4331	$13,183	$3,502
Supplies cost (1200*4*PVF) & (3480*PVF)	1-5	3.4331	$16,479	$11,947
Dispoal Value of Machine ($1900XPVF)	5	0.5194		-$987
Npv of each contract			$253,214	$233,638

Finally Kodak contract is favourable to company the NPV is -19576
