  1. Answer:
    Information is missing on the price of electricity.
    Step-by-step explanation:
    There is information missing on the cost of the electricity, per kwh.  b(x) = ????.
    If it is $0.20/kwh, then we would have:
    b(x) = $0.20x
    b(800) = $0.20*(800)
    b(800) = $160
    It depends on the price.
