Question 1
Essay
A nuclear power plant is planning to replace the outdated equipment with more environmental- friendly equipment. The new equipment has an initial cost of $410,000. The equipment is expected to yield an annual savings of $190,000 each year for the first 4 years and $191,200 each year thereafter. The MACRS with a 15- year recovery period is to be used for tax purposes. Should the equipment be purchased if the equipment will be sold for $148,263.00 at the end of year 10? Assume an effective tax of 38% and a before- tax MARR of 16.13% per year.
Question 2
Short Answer
An inspecting and profiling web controller that costs $40,000 has a life of 8 years with a $5000 salvage value. The estimated annual operating and maintenance cost is $3700 per year. Use classical straight line depreciation to determine the annual depreciation at the end of year 5.
Question 3
Short Answer
New spray coating equipment costs $24,000 is to be used in an oversea shipyard. It has a 12- year life and an estimated salvage value of $4750. If the global naval shipbuilding company uses MACRS with an ADS recovery period to calculate the depreciation and book value for the new coating equipment, determine the annual depreciation and book value at the end of year 7.
Question 4
Short Answer
An engineer- to- order manufacturer is considering purchasing new equipment for its film adhesive assembly. The initial cost of the equipment is $12,100 and annual maintenance costs are estimated to be $185,000 per year. Annual operating costs will be in direct proportion to the hours of use at $12 per hour. The expected annual revenue is $220,000 per year. The equipment has a salvage value of $500 at the end of 5 years. What is the maximum annual hours of use for which the equipment is economically justified? Use straight- line depreciation, an effective tax rate of 39%, and an after- tax MARR of 16% per year.
Question 5
Essay
A private metropolitan mass transit system operator wants to add a new trolleybus to its fleet. The following information is prepared for the economic evaluation. Either trolley is to be used for 8 years and sold for the estimated salvage value. The before- tax MARR is 12.31% per year and the effective tax rate is 35%. Using SL depreciation, select a machine on the basis of after- tax annual worth analysis.
Question 6
Short Answer
A piece of liquid handling equipment that costs $10,000 has a $3000 salvage value. Using MACRS depreciation with a 3- year recovery period, calculate the accumulated annual depreciation at the end of year 3.
Question 7
Essay
A viscosity sensing instrument costs $46,000 and has a $5500 salvage value with a 7- year recovery period. The estimated annual operating cost is $3000 per year. Use classical straight line depreciation to calculate the cumulative depreciation and a book value at the end of year 6.
Question 8
Short Answer
A coil winding and unwinding machine that costs $32,000 has a life of 9 years with a $4000 salvage value. Use classical straight line depreciation to determine the book value after 7 years.
Question 9
