Cost of electricity [ I have a machine that consumes 125kW. Calculate the cost of the electricity it uses depending on when I turn it on and off. Use military time. I can turn it on any time between 0 and 24 . Similarly, I can turn it off any time between 0 and 24. Examples: Time on: 7 Time off: 18 Cost =125(127)0.75+125(1812)1.2 Time on: 13 Time off: 3 Cost =125(2413)1.2+125(30)0.75 Time on: 10 Time off: 7 Cost=125(1210)0.75+125121.2+125(70)0.75
