    Answer:

    The equation that models the scenario is y=40x+75.

    Step-by-step explanation:

    Given:

    Charges for a service call is $75.

    Charges for per hour time spent is $40.

    Now, to give an equation that models it.

    So, the rate of change for additional hours means rate per hour.

    Let the number of hours be x.

    And the total fee charged by the plumber be y.

    The slope of rate of change be m

    By putting the formula for the slope of line:

    y=mx+c

    y=40x+75

    So, the slope of line of function = y=40x+75

    Therefore, the equation that models the scenario is y=40x+75.
