.[35] In an industrial facility, four energy conservation measurements are realized. For the first two measurements, energy savings of 150kWh and 100kWh are achieved with a cost of conserved energy (CCE) of 2/kWh and 4 c/kWh, respectively. For the last two measurements, energy savings of (250+10 Row\#) kWh and (100+10 Row\#) kWh are realized with a CCE of X/kWh and Y/kWh, respectively. If a relation of XY=20 exists, calculate a) The costs X and Y to get minimum average CCE value b) The minimum average CCE value (corresponding to X and Y found in part a)
