Now, calculate the PV using the differential approach. (Enter the present value factor to four decimal places, "X.XXXX." Round dollar amounts to the nearest whole number. Use a minus sign or parentheses for a negative net present value.) Requirement 2. Should Northeastern keep the Xerox copiers or replace them if the decision is based solely on the given data? The Xerox machines be replaced by the Brother equipment. Northeastern University is considering replacing some Xerox copiers with faster copiers purchased from Brother. The administration is very concerned about the rising costs of operations during the last decade. (Click the icon to view the view information on the Xerox and Brother copiers.) (Click the icon to view the present value factor table. (Click the icon to view the present value annuity factor table.) Read the requirements. Requirement 1. Using DCF techniques, compute the PV of all relevant cash flows, under both alternatives, for the 10-year period discounted at 12%. As a nonprofit university, Northeastern does not pay income taxes. Begin by completing the NPV using the total project approach. First, complete the "replace" option and then complete the "keep" option and calculate the difference in NPV between the alternatives. (Enter the present value factor to four decimal places, "X.XXXX." Round dollar amounts to the nearest whole number. Use a minus sign or parentheses for annual net cash outflows and for a negative net present value.) To convert to Brother, two operators would have to be retrained. Required training and remodeling would cost $7,500. Northeastern's three Xerox machines were purchased for $18,000 each, 5 years ago. Their expected life was 15 years. Their resale value now is $2,750 each and will be zero in 10 more years. The total cost of the new Brother equipment will be $30,000; it will have zero disposal value in 10 years. The three Xerox operators are paid $12 an hour each. They usually work a 40 -hour week. Machine breakdowns occur monthly on each machine, resulting in repair costs of $60 per month and overtime of 9 hours, at time-and-one-half, per machine per month, to complete the normal monthly workload. Toner, supplies, and so on, cost $50 a month for each Xerox copier. The Brother system will require only two regular operators, on a regular work week of 40 hours each, to do the same work. Rates are $16 an hour, and no overtime is expected. Toner, supplies, and so on, will cost a total of $2,100 annually. Maintenance and repairs are fully serviced by Brother for $1,000 annually. (Assume a 52-week year.)
