    Isaiah uses 1,275 kWh of electricity

    = 400 kWh + 875kWh

     

    Standard use plan:

    7.5 cents/kWh for the first 400 kWh

    10 cents/kWh for anything over 400 kWh

     

    With standard use plan, Isaiah would pay:

    7.5 * 400 cents + 10 * 875 cents

    = 3,000 cents + 8,750 cents

    = 11,750 cents

    = $117.50

     

    Isaiah uses 1,275 kWh of electricity

    On-peak usage = 575 kWh

    Off-peak usage = 1,275kWh – 575kWh = 700kWh

     

     

    Interval use plan:

    On-peak hours – 15 cents/kWh

    Off-peak hours – 3 cents/kWh

     

    With Interval use plan, Isaiah would pay:

    15 * 575 cents + 3 * 700 cents

    = 8,625 cents + 2,100 cents

    = 10,725 cents

    = $107.25

     

    Answer: Option A

    Standard use plan – $117.50

    Interval use plan – $107.25
