3. A specialty concerete mixer used in construction is purchased for $300,000 seven (7) years ago.Its annual O&M costs are $105,000. At the end of 8 year planning horizon, the mixer has a salvage value fo $5,000. If the mixer is replaced the new mixer will require initial investment of $375,000.At the end of 8 year planning horizon, it will have a salvage value of $45,000. Its annual O&M costs will be only $40,000 due to newer technology.
Analayze using EUAC measure and MARR of 15% to see if the mixer should be replaced if the older mixer is sold for market value of $65,000.
a. Use cash flow approach (insider's viewpoint approach)
4. Logan Public Library is planning a renovation. Cost including cabling will be $33,000, new equipment will cost $21,000 and e-volume access initiation will be $17,500. Maintenance is expected to run another $3,500 per year plus $4,000 for renewed e-volume access. The interest rate is 8%, planning horizon is 10 years,
and renovation is expected to have a salvage value of 30% with no salvage value for equipment or e-access.
It's estimates that visits will increase by 2,500 in the first year and 500 per year thereafter.
If it's estimated that the average benefits due to new facilities and equipment, access will be $2.00 per person per visit.
a. Should the city approve the plans? Use PW and calculate B-C.
b. What is the smallest benefit per person that will make this project desirable?
