    3*1200*365 = 1,314 kWH

    if the rates are $5/kWH, $6/kWH, and $7/kWH, then the cost would be:

    $6,570, $7,884, and $9,198

    Lol slaps, if energy was $5, $6 and $7 a kWh this world would be a very different place. As the other guy said, move the decimal two places to the left and then the answers are correct.

    You should do your own homework in the future though.
