Giving the following information on machine A and machine B and assuming an 8.6% MARR, which mutually exclusive alternative should be selected?
The City of Manila contemplates to increase the capacity of its existing water transmission line. Two plans are under consideration. Plan A requires the construction of a parallel pipe line, the flow being maintained by gravity. The initial cost is P2,750,000 and the life is 40 years, with an annual operating cost of P50,000.
Plan B requires the construction of a booster pumping station costing P1,050,000 with a life of 40 years. The pumping equipment costs an additional amount of P250,000. It has a life of 20 years and a salvage value of P25,000. The annual operating cost is P165,000.
If the interest rate is 12%, which is the more economical plan and by how much lower than the other?
Plan B lower than Plan A by P115,906.57
Plan B higher than Plan A by P15,906.57
Plan A higher than Plan B by P15,906.57
Plan A lower than Plan B by P115,906.57
Two 150-horsepower (HP) motors are being considered for installation at amunicipal sewage treatment plant. The first costs $4,500 and has an operating efficiency of 83%. The second costs $3,600 and has an operating efficiency of 80%. Both motors are projected to have zero salvage value after a life of 10 years. All the annual charges, such as insurance and maintenance, amount to a total of 15% of the original cost of each motor. If power cost is a flat 5 cents per kilowatt-hour, which alternative should be chosen at 5,000 operating hours per year? Assume an interest rate of 6%. (A conversion factor you might find useful is IHP = 746watts = .746kilowatts.)

The expected output is 8 tons per hour. Annual maintenance and operating cost is expected to be Php3,500.
