Majdy Corporation purchased a machine 5 years ago for JOD 527,000 when it launched product X. Unfortunately, this machine has broken down and cannot be repaired. The machine could be replaced by a new model machine "M1" costing JOD 545,000 or by a new model "M2" machine costing JOD 450,000. Management has decided to buy the model "M2" machine. It has less capacity than the model "M1" machine, but its capacity is sufficient to continue making product X. Management also considered, but rejected, the alternative of dropping product X and not replacing the old machine. If that were done, the JOD 450,000 invested in the new machine could instead have been invested in a project that would have returned a total of JOD 532,000.
1. What is the amount of sunk cost if the decision was to buy model "M2" machine rather than the model "M1" machine?
2. What is the amount of opportunity cost if the decision was to invest in model "M2" machine?

8 years ago a company installed a robot that today has a market value of $ 60,000 and each year it drops $ 2000. For example, at the end of the first year the market value will be $ 58,000 and so it continues to decline. Maintenance costs for the next 4 years are estimated at $ 3000 this year and increasing 10% each year. Determine the marginal cost of extending the service for one year, for the next 4 years if the MARR is 12%. Fill in the blanks with the results.

- A company purchased a piece of equipment five years ago. A new piece of machinery is being considered for the assembly line because of increasing maintenance costs for this equipment. The cost characteristics of the old equipment and the proposed replacement are shown below: Old Equipment Proposed Replacement Original cost = $18,000 Maintenance = $1000 in year one(four years ago) increasing by $200 per year Market Value(MV) at end of life = 0 Original estimated life = nine years Suppose a $12,000 MV is available now for the old equipment. Perform a before-tax analysis, using a before tax MARR of 12%, with NAW-C or EUAC to determine which alternative to select. Be sure to utilize a uniform gradient in your analysis of the old equipment and account for all cash flows. Purchase cost = $21.000 Maintenance $250 per year Market Value(MV) at end of life = $5.000 Estimated life = five yearsarrow_forwardHayden Inc. has a number of copiers that were bought four years ago for $27,000. Currently maintenance costs $2,700 a year, but the maintenance agreement expires at the end of two years, and thereafter, the annual maintenance charge will rise to $8,700. The machines have a current resale value of $8,700, but at the end of year 2, their value will have fallen to $4,200. By the end of year 6, the machines will be valueless and would be scrapped. Hayden is considering replacing the copiers with new machines,that would do essentially the same job. These machines cost $32,000, and the company can take out an eight-year maintenance contract for $1,000 a year. The machines would have no value by the end of the eight years and would be scrapped.

Its market value is now $15,000 and is expected to decline by 10%/year over the next five years. It is projected that this machine will be operational for another five years, after which time it will be scrapped (no salvage value). This year, its annual costs are estimated as $1500, but will increase by $1000/year thereafter. A new machine is now available for $20,000. It has no annual costs over its five-year minimum cost life (i.e., economic life). Using an 8% MARR, when (if at all) should the existing machine be replaced with the new machine?

If the crane is kept in service, it must be overhauled immediately at a cost of $5,000. Operating and maintenance costs will be $3,000 per year after the crane is overhauled. The overhauled crane will have zero MV at the end of the 8-year study period. A new crane will cost $20,000, will last for 8 years, and will have a $4,000 MV at that time.

- A machine for refining operation was purchased 7 years ago for 160,000 SAR. Last year a replacement study was performed with the decision to retain it for 3 more years. The situation has changed . The equipment is estimated to have a value of 8,000 SAR now or anytime in the future. If kept in service, it can be minimally upgraded at a cost of 43,000 SAR which will make it usable for up to 2 more years. Its operating cost is expected to be 22,000 SAR the first year and 25,000 SAR the second year.arrow_forwardThe replacement of a planning machine is being considered by the Reardorn Furniture Company.

The machine can now be upgraded at a cost of $70,000 or sold to a small business for $40,000. The current machine will have an annual operating cost of $85,000. If upgraded, the currently owned machine will be in service for 3 years more and later it will be replaced with a machine that will be used in the manufacture of various lines of products. This replacement machine, which will serve the company now and for at least 8 years to come, will cost $220,000. Its salvage value will be $50,000 in years 1 through 5; $20,000 after 6 years, and $10,000 thereafter. This will have an estimated operating cost of $65,000 per year.
