    Answer:

    2000

    Step-by-step explanation:

    A(m) = 100 + 0.20m

    B(m) = 80 + 0.3m

    —————————

    For company A to have a better deal, the truck must be driven more than __ miles per day.

    Solve::

    100 + 0.2m < 80 + 0.3m

    ——-

    20 < 0.1m

    m > 2000/1 = 2000 miles

    —————

    2500 mi
