    Answer-

    A - Inequality \ equation= 960d-680d > 52000

    B -Julianne \ begin \ making \ a \ profit \ after \ 186 \ days

    Solution-

    Julianne’s start-up cost = $52,000

    Daily operating costs = $680

    Daily earnings = $960

    And the number of days = d

    The inequality that represents this situation,

    960d-680d > 52000

    d(960-680)>52000

    In order to be in profit, she must surplus the initial investment and the daily expenses. The time taken by her to be in profit,

    d>\frac{52000}{960-680} > 185.71 \approx 186

    d > 186 \ days

    ∴ So after 186 days of starting the business, she will start making profits.
