A manufacturer is considering replacing a production machine tool. The new machine, costing $3700, would have a life of 4 years and no salvage value, but would save the firm $500 per year in direct labor costs and $200 per year indirect labor costs. The existing machine tool was purchased 4 years ago at a cost of $4000. It will last 4 more years and will have no salvage value at the end of that time. It could be sold now for $1000 cash.Assume that money is worth 8% and that the difference in taxes, insurance, and so forth, for the two alternatives is negligible. Use an annual cash flow analysis to determine whether the new machine should be purchased.
A factory with capacity of 700,000 units per year operates at 62% capacity. The annual income is $430,000.00. Annual fixed costs are $190,000.00 and the variable costs are $0.348 per unit.
a) What is the current loss or profit?
b) What is the breakeven point?.
A specialty concrete mixer used in construction was purchased for $300,000 7 years ago. Its annual O&M costs are $105,000. At the end of the 8-year planning horizon, the mixer will have a salvage value of $5,000. If the mixer is replaced, a new mixer will require an initial investment of $375,000. At the end of the 8-year planning horizon, it will have a salvage value of $45,000. Its annual O&M cost will be only $40,000 due to newer technology. Analyze this using an EUAC measure and a MARR of 15 percent to see if the concrete mixer should be replaced if the old mixer is sold for its market value of $65,000.
a. Use the cash flow approach (insider’s viewpoint approach)
b. use the opportunity cost approach (outsiders viewpoint approach)

The old equipment's trade-in value last year was $4000 and its value this year is $2000. The operating cost was $700 last year. If bought last year, the new equipment would have cost $13K, the salvage value after 8 years would be $2000, and it would have an annual operating cost of $4000. If bought last year, what would have been the EUAC of the new equipment (in dollars) at 16% interest rate per year?

- A potential project is currently under review. An initial investment of 87000 would be necessary for equipment. The annual revenues and expenses are expected to be 40000 and 19000 each year, respectively, over the 6-year project period. The salvage value of the equipment at the end of the project period is projected to be $17000. Assume a MARR of 9%. Find the PW (to the nearest cent).arrow_forwardsolve it manually; do not use excel A steel pedestrian overpass must either be reinforced or replaced. Reinforcement would cost $25,000 and would make the overpass adequate for an additional 6 years of service. If the overpass is torn down now, the scrap value of the steel would exceed the removal cost by $15,000. If it is reinforced, it is estimated that its net salvage (market) value would be $18,000 at the time it is retired from service. A new pre-stressed concrete overpass would cost $140,000 and would meet the foreseeable requirements of the next 40 years. Such a design would have no net scrap or MV. It is estimated that the annual expenses of the reinforced overpass would exceed those of the concrete overpass by $3,200. Assume that money costs the state 8% per year and that the state pays no taxes.

The new car she is considering will cost $ 18,000 to buy, $ 1,500 per year to insure, and $ 500 per year for maintenance after the 3-year warranty expires. She would keep the car for 7 years when it will have a salvage value of $ 7,000. She has found a 2-year-old car that is the same model for $ 13,000. The 3-year warranty is transferrable, so the annual maintenance cost of $500 starts in year 2. Because the car is less valuable, insurance is $300 per year less than for the new car. After 5 years, the vehicle will be 7 years old and will have the same salvage value of $ 7,000. Rebecca is ignoring costs for fuel, oil, tires and registration, because the two vehicles will have the same costs.
