company is planning to install solar panels to provide some of the electricity to a new building for 10 years. the installation phase will cost $30000 in year 1 and $50000 in year 2. This solar installation will result in supplying electrical energy of $20000 in year 3 to year 5, $30000 in year 6, and amounts increasing by $2000 each year through year 10. comes with free maintenance. find the minimum rate of return set by the company at 10% per year.
Heat loss through the walls of a heating system means an annual cost of $800,000. An insulation system that would reduce this loss by 33% could be installed for $500,000 and another that would reduce this loss by 20% could be installed for $300,000. Determine if any isolation systems should be used. Assume that the system will be used for 8 years, and that the Attractive minimum rate of return is 5% per year.
What is the present equivalent of RM 25,000 to be received in 20 years wheninterest rate is 6% per year componded semiannually?.

    El Paso Water (EPW) purchases surface water for treatment and distribution to EPW customers from the County Water Improvement District during the irrigation season. A new contract between the two entities resulted in a reduction in future price increases in the cost of the water from 8% per year to 4% per year for the next 20 years. The cost of water next year (which is year 1 of the new contract) will be $260 per acre-ft. Using an interest rate of 6% per year, (a) Determine the present worth of the savings (in terms of $/acre-ft) to EPW between the old and the new contracts. (b) Determine the total present worth of the savings over the life of the contract if EPW uses 51,000 acre-ft per year.
