Please no written by hand solution 1. The Energetic company needs to make plans for the energy systems for a new building. Theenergy needs in the building fall into three categories: (1) electricity, (2) heating water, and(3) heating space in the building. The daily requirements for these three categories (allmeasured in the same units) are 20 electricity units, 10 heating water units, and 30 spaceheating units. The three possible sources of energy to meet these needs are electricity, naturalgas, and a solar heating unit that can be installed on the roof. The size of the roof limits thelargest possible solar heater to 30 units, but there is no limit to the electricity and natural gasavailable. Electricity needs can be met only by purchasing electricity (at a cost of 50 KWDper unit). Both other energy needs can be met by any source or combination of sources. Theunit costs are given in the following table.WaterheatingSpaceheatingElectricity90 KWD80 KWDNatural Gas60 KWD50 KWDSolar Heater30 KWD40 KWDThe objective is to minimize the total cost of meeting the energy needs.a. Define the decision variables.b. Formulate and solve a linear program to minimize the energy costs of meeting theenergy needs.c. Which heating requirement (water or space) would you consider reducing tolower cost? Explain.

1. Power Notebooks, Inc. plans to manufacture a new line of notebook computers. Management is trying to decide whether to purchase the LCD screens for the computers from an outside supplier or to manufacture the screens in-house. The screens cost $100 each from the outside supplier. To set up the assembly process required to produce the screens in-house would cost $100,000. The company could then produce each screen for $75. The number of notebooks that eventually will be produced (Q) is unknown at this point. a. Set up a spreadsheet that will display the total cost of both options for any value of Q. Use trial-and-error with the spreadsheet to determine the range of production volumes for which each alternative is best. b. Use a graphical procedure to determine the break-even point for Q (i.e., the quantity at which both options yield the same cost). 2.
