Salim Service company owns several taxis that were purchased four years ago for
$27000 each. The current market value is $10000 each. If they are kept for another
6 years, they can be sold for $2000 each. The annual maintenance cost per cab is
$900 a year. Salim Service is looking at replacing the cabs with the option to lease
new cabs at an annual cost of $9000 per year per cab which includes free
maintenance. How much more would it cost them per year to switch to leasing?
Assume an interest rate of 9%.
3. Angstrom Technologies intends for the company to use the newest and finest equipment in its labs. Precision measurement
equipment was purchased 7 years ago for $160,000. Last year a replacement study was performed with the decision to retain for 3
more years. The situation has changed. The equipment is estimated to have a value of $8000 if "scavenged" for parts now or
anytime in the future. If kept in service, it can be minimally upgraded at a cost of $43,000 to make it usable for up to 2 more years.
Its operating cost is estimated at $22,000 the first year and $25,000 the second year. Alternatively, the company can purchase a
new system that will have an equivalent annual worth of $47,063 per year over its ESL. The company uses a MARR of 10% per year.
Use annual worth analysis to determine when the company should replace the machine.

- 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 and at the end of the 8-year planning horizon, the new mixer will have a salvage value of $45,000. Its annual O&M cost will be only $40,000 due to newer technology. Use an EUAC measure and a MARR of 15% to see if the concrete mixer should be replaced if the old mixer is sold for its market value of $65,000. Solve, a.

- Last year, a decision was made to keep the same equipment in lieu of buying new equipment. 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 $11K, 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 17% interest rate per year?
