A food processing plant consumed 600,000 kW of electric energy annually and pays an average ofP2.00 per kWh. A study is being made to generate its own power to supply the plant the energy required, and that the power plant installed would cost P2,000,000. Annual operation andmaintenance,P800,000. Other expenses P100,000 per year. Life of power plant is 15 years; salvage value at the end of life is P200,000 annual taxes and insurances, 6% of first cost; and rate of interest is 15%. Using the sinking fund method for depreciation, determine if the power plant is justifiable. Compute using the present worth, annual worth, and rate of return.

1. You are valuing a 10-acre vacant lot with a septic system and a well on site. The size adjustment factor for 10 acres is 2.23. You have found two recent sales to use as comparables. -Sale 1 is 3.5 acres in size and has a septic system and a well on site. It sold for $200,000. The corresponding size adjustment factor for 3.5 acres is 1.57. -Sale 2 is 7 acres in size and sold for $225,000. However, it does not have a septic system or a well, which will cost $50,000 total to install. The corresponding size adjustment factor for 7 acres is 1.93. CALCULATE THE RANGE OF THE VALUE OF THE 10-ACRE VACANT LOT ADJUSTED FOR SIZE, ROUNDED TO THE NEAREST $1,000. SHOW YOUR WORK
