A remotely located air sampling station can be powered by solar cells or by running an electric line to the site and using conventional power. 1. Solar cells will cost $10,500 to install and will have a useful life of 4 years with no salvage value. Annual costs are expected to be $1,950. 2. A new power line will cost $17,500 to install, with power costs expected to be $950 per year. The salvage value of the line is considered to be zero with useful life of 4 years. At an interest rate of 15% per year, which alternative should be selected on the basis of a future worth analysis?

Compare two alternatives for a physical security system surrounding a power distribution substation using annual worth analysis and a MARR of 10% per year. System Condi Torro First cost, $ −25,000 −130,000 M&O cost, $ per year −9,000 −2,500 Salvage value, $ 3,000 100,000 Life, years 3 ∞
Car A costs $800 more than Car B, but it consumes 0.035 gallons/mile versus 0.06 gallons/mile for Car B. Both vehicles last 10 years and B's salvage value is $175 smaller than A's. Fuel costs $2.30/gallon. Other things being equal, beyond how many miles of use per year (x) does A become preferable to B?
Guardian is a national manufacturing company of home health care appliances. It is faced with amake-or-buy decision: a newly engineered lift can be installed in a car trunk to raise and lower awheelchair.Buy: The steel arm of the lift can be purchased for $0.60 per unit or make in house.Make: If manufactured on site, two machines will be required. Machine A is estimated to cost$18,000, have a life of 6 years, and a $2,000 salvage value. Machine B will cost $12,000, have a life of4 years, and a $-500 salvage value (carry-away cost). In addition, machine A will require anoverhaul after 3 years costing $3,000. The AOC for A is expected to be $6,000 per year and for B$5,000 per year. A total four operators will be required for the two machines at a rate of $12.50 perhour per operator. 1,000 units will be manufactured in a normal 8-hour period.Use MARR=15% to find the number of units to be manufacture each year
Two machines can be used to produce a part from titanium. The costs and other cash flows associated with each alternative are estimated. The salvage values are constant regardless of when the machines are replaced. Determine which alternative(s) should be selected for further analysis if alternatives must have a payback of 5 years or less. Perform the analysis with (a) i = 0%, and (b) i = 10% per year. Machine Semiautomatic Automatic First cost, $ −40,000 −90,000 Net annual income, $ per year 10,000 15,000 Maximum life, years 10 10 Salvage value, $ 0 0
A tractor for over-the-road hauling is to be purchased by AgriGrow for $90,000. It is expected to be of use to the company for 6 years, after which it will be salvaged for $4,000. Transportation cost savings are expected to be $170,000 per year; however, the cost of drivers is expected to be $70,000 per year and operating expenses are expected to be $63,000 per year, including fuel, maintenance, insurance and the like. The company’s income-tax rate is 25% and MARR is 10% on after-tax cash flows. Suppose that, to AgriGrow’s surprise, they actually dispose of the tractor at the end of the 4th tax year for $6,000. Develop tables using a spreadsheet to determine the ATCF for each year and the after-tax PW, AW, IRR, and ERR after only 4 years. Use MACRS-GDS and state the appropriate property class. Only calculate PW and IRR
Car A initially costs 500 more than car B. but it consumes 0.04 gallon/mile versus 0.05 gallon/mile for B. Both vehicles last 8 years, and B's Salvage value S 100 smaller than A's. Fuel costs S 1.7 per gallon. Other things being equal. beyond how many miles of use per year does car A become preferable to car B
A drug store is looking into the possibility of installing a 24/7-automated refill system to increase its projected revenues by ₱800,000 per year over the next 5 years. Annual expenses to maintain the system are expected to be ₱200,000. The system will cost ₱2,000,000 and will have no market value at the end of the 5-year study period. The store’s MARR is 20% per year. Using the AW (annual worth) method, it can be concluded that this is not a good investment. True or False? Why?
Help....... Solve Write Company has a maximum capacity of 200,000 units per year. Variable manufacturing costs are $12 per unit. Fixed overhead is $600,000 per year.

Lennon Hearth Products manufactures glass-door fireplace screens that have two types of mounting brackets for the frame. An L-shaped bracket is used for relatively small fireplace openings and a Ushaped bracket is used for all others. The company includes both types of brackets in the box with their product and the purchaser discards the one not needed. The cost of these two brackets with screws and other parts is $3.50. If the frame of the fireplace screen is redesigned, a single universal bracket can be used that will cost $1.20 to make. However, initial costs of retooling ($6000) and inventory writedowns ($8000) will be incurred immediately. If the company sells 1200 fireplace units per year, should the company keep the old brackets or go with the new ones, assuming the company uses an interest rate of 15% per year and it wants to recover its investment in 5 years. Use the present worth method for your evaluation.
