A machine costs $19,310 and is expected to have a scrap value of $2,991 whenever it is retired. Operating and Maintenance costs are $1,047 for the first year and expected to increase by $1,751 thereafter. If the MARR is 12%, determine the minimum equivalent uniform annual cost associated with the optimal economic life of the machine. The service life of this machine is 5 years. Note: round your answer to two decimal places, and do not include spaces, currency signs,
XYZ Company purchased a machine six years ago for $350,000. Last year a replacement study was performed with
the decision to retain the machine for 2 more years. However, this year the situation has changed. The machine is
estimated to have a value of only $8,000 now and if it is to be kept in service, upgrading at a cost of $50,000 will be
necessary to make it useful for up to 2 more years. Operating cost is expected to be $10,000 the first year and $15,000
the second year, with no salvage value at all. Alternatively, the company can purchase a new machine with an ESL
of 7 years, no salvage value, and an equivalent annual cost of $ -55,540 per year. The MARR is 10% per year. Using
the estimates above, determine
a) When the company should replace the upgraded machine?

- Hayden 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.

If repaired, the old machine can be used for another five years although the firm does not expect to realize any salvage value from scrapping it in five years. Alternatively, the firm can sell the machine to another firm in the industry now for $5,000. If the machine is kept, it will require an immediate $1,200 overhaul to restore it to operable condition. The overhaul will neither extend the service life originally estimated nor increase the value of the inspection machine. The operating costs are estimated at $2,000 during the first year and are expected to increase by $1,500 per year thereafter. Future market values are expected to decline by $1,000 per year. The new machine costs $10,000 and will have operating costs of $2,000 in the first year, increasing by $800 per year…arrow_forward

These cost $75 000 each, including the charging stand. In practice, it was found that they did not hold a charge as long as claimed by the manufacturer, so operating costs are very high. This also results in their currently having a salvage value of about $10 000. Chatham is considering replacing them with propane models. The new ones cost $58000. After one year, they have a salvage value of $40 000, and thereafter decline in value at a declining-balance depreciation rate of 20 percent, as does the electric model from this time on. The MARR is 8 percent. Operating costs for the electric model are $20 000 over the first year, rising by 12 percent per year. Operating costs for the propane model will initially be $10 000 over the first year, rising by 12 percent per year. Should Chatham Automotive replace the forklifts now?arrow_forward

- Julie’s Bakeshop bought a loaf bread machine for P500,000 on June 1, 2010. It is estimated that it will have a useful life of 10 years, a scrap value of P10,000, production of 400,000 loaves of bread and working hours of 150,000. The company uses the machine for 15,000 hours in 2010 and 20,000 hours in 2011. The machine produces 40,000 loaves in 2010 and 50,000 loaves in 2011.

The old machine was used to make product 143L until it broke down last week. Unfortunately, the old machine cannot be repaired. Management has decided to buy the new model 220 machine. It has less capacity than the new model 370 machine, but its capacity is sufficient to continue making product 143L. Management also considered, but rejected, the alternative of simply dropping product 143L. If that were done, instead of investing $405,000 in the new machine, the money could be invested in a project that would return a total of $456,000. In making the decision to invest in the model 220 machine, the opportunity cost was:arrow_forwardGeorgia Ceramic Company has an automatic glaze sprayer that has been used for the past 10 years. The sprayer can be used for another 10 years and will have a zero salvage value at that time. The annual operating and maintenance costs for the sprayer amount to $15,000 per year. Due to an increase in business, a new sprayer must be purchased, either in addition to or as a replacement for the old sprayer. Option 1: if the old sprayer is retained, a new, smaller capacity sprayer will be purchased at a cost of $48,000; this new sprayer will have a $5,000 salvage value in 10 years and an annual operating and maintenance costs of $12,000. The old sprayer has a current market value of $6,000. Option 2: if the old sprayer is sold, a new sprayer of larger capacity will be purchased for $84,000. This sprayer will have a $9,000 salvage value in 10 years and annual operating and maintenance costs of $24,000. Which option should be selected at MARR = 12%.arrow_forward
