The initial cost of a packed-bed degassing reactor for removing trihalomethanes from potable water is $84,000. The annual operating cost for power, site maintenance, etc. is $13,000. If the salvage value of the pumps, blowers, and control systems is expected to be $9000 at the end of 10 years, the AW of the packed-bed reactor, at an interest rate of 8% per year, is closest to: (a) $−26,140 (b) $−25,518 (c) $−24,900 (d) $−13,140
A company that manufactures high-speed submersible rotary-indexing spindles is considering an upgrade of production equipment to reduce costs over the next 5 years. The company can invest $80,000 now, 1 year from now, or 2 years from now. Depending on when the investment is made, the savings will vary. The saving estimates are $26,000, $31,000, or $37,000 per year if the investment is made now, 1 year from now, or 2 years from now, respectively. The company will only invest if the ROR is at least 20% per year. Using a future worth analysis, determine if the timing of the investment will affect the return requirement and, if so, when the investment should be made. Solve by (a) hand, and (b) spreadsheet.
Adams Manufacturing spent $30,000 on a new sterilization conveyor belt, which resulted in a cost savings of $4202 per year. The length of time it should take to recover the investment at 8% per year is closest to: (a) Less than 6 years (b) 7 years (c) 9 years (d) 11 years
