NEV, Inc. wants to evaluate two new methods that will improve their productivity. Both alternatives have 22 years of service life and NEV uses MARR of 13%. Alternative A has a first cost of $3,315,000 Maintenance cost will start end of year three due to an incentive in the contract with the manufacture that will give free maintenance in the first 2 years. The maintenance cost at end of year three is $42,000 and will increase by $2,700 starting end of year four and continue to increase with the same value thereafter till the end of its service life. A three-times major repair will occur. The first one is at end of year 8 that will cost $56,000, the second one is at end of year 13 and will cost $32,000 and the third and last major repair is $27,500 at end of year 19. The expected revenues from this alternative are $572,000 per year starting end of year 1 and this option will have a salvage value of $840,000 at the end of its service life. Alternative B has a first cost of $2,570,000 and…
The Ecology Group wishes to purchase a piece of equipment for recycling of various metals. Machine 1 costs $123,000, has a life of 10 years, an annual cost of $5000, and requires one operator at a cost of $24 per hour. It can process 10 tons per hour. Machine 2 costs $70,000, has a life of 6 years, an annual cost of $2500, and requires two operators at a cost of $24 per hour each to process 6 tons per hour. Assume i = 7% per year and 2080 hours per work year. Determine the annual breakeven tonnage of scrap metal at i = 7% per year and select the better machine for a processing level of 1500 tons per year.
In a cold storage plant, it is desired to determine whether to use insulation two inches thick or three inches thick in insulating the walls of the cold storage ware house. Heat absorb through the walls without insulation would cost P96.00 per year per square meter. A two-inch insulation will cost P30.40 per square meter and will cut out 89% of the loss. A three-inch insulation will cut out 92% of the loss and will cost P65.00 per square meter. Using a life 15 years for the insulation with no salvage value and a minimum attractive return of 8%, what thickness of insulation should be used?
