A food processing plant consumes 600,000 kW-hr of electrical energy
annually and pays an average of P 2.00 per kW-hr. A study is being made to
generate its own power to supply the plant the energy required. The power
plant installed, costs P 2,000,000; annual operation and maintenance, P 800,
000; other expenses, P 100,000 per year. The life of the plant is 15 years;
salvage value at the end of life is P 200,000; annual taxes and insurance 6%
of first cost, and the rate of interest is 15 %. Using the sinking fund method
