Enter your answer in this format: 123456.78 A manufacturing company is considering a capacity expansion investment at the cost of $242,047 with no salvage value. The expansion would enable the company to produce up to 31,240 parts per year and the useful life of the additional capacity is seven years. Each part would generate $2.95 net prot and annual operating and maintenance costs are estimated at $29,951 per year. The market demand for the parts is unlimited, all parts produced will be sold. The MARR of the rm is 10%. The minimum annual production rate to make this investmentjustiable is: Enter your answer in this form: 12345.67 A machine that produces a certain piece must be turned off by the operator after each piece is completed. The machine "coasts" for 15 seconds after it is turned off, thus preventing the operator from removing the piece quickly before producing the next piece. An engineer has suggested installing a brake that would reduce the coasting time to 3 seconds. The machine produces 50,000 pieces a year. The time to produce one piece is 1 minute 45 seconds, excluding coastint time. The operator earns $9 an hour and direct costs for operation are $4 an hour. The direct costs are incurred whenever the operator has to work. The brake will require servicing every 468 hours of operation. It will take the operator 30 minutes to perform the necessary maintenance and will require $57 in parts and material. The brake is expected to last 7,500 hours of operation (with proper maintenance) and will have no salvage value. How much could be spent for the brake if the Minimum Attractive Rate of Return is 10% compounded annually? Enter your answer in this format: 1234.56
