Economy Movers charge $85 plus $40 an hour to move households across town. Helpful Moving Company charges $60 an hour for cross-town moves. For what lengths of time is Helpful Moving Company more expensive?

    I'm sure there's an algebraic method of determining this.

    However, trial and error will also get the answer.

    85 + 40 = 125
    85 + 80 = 165
    85 + 120 = 205
    85 + 160 = 245

    60
    120
    180
    240

    A= Total charges of Economy Movers in t hours.

    B= Total charges of Helpful Moving Company in t hours.

    Write an inequality B>A to determine t.
