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. Use the cash flow approach (insider’s viewpoint approach). b. Use the opportunity cost approach (outsider’s view point approach).arrow_forwardComplete each problem in excel.

The sprayer's base price is $830,000, and it would cost another $22,500 to install it. The machine falls into the MACRS 3-year class, and it would be sold after 3 years for $485,000. The MACRS rates for the first three years are 0.3333, 0.4445, and 0.1481. The machine would require an increase in net working capital (inventory) of $17,500. The sprayer would not change revenues, but it is expected to save the firm $351,000 per year in before-tax operating costs, mainly labor. Campbell's marginal tax rate is 25%.
