    Answer:

    200 minutes

    Step-by-step explanation:

    Let x minutes is needed to use for the cell phones to coast the same amount.

    Now, f(x) = 35 + 0.11x …….. (1) {As per given conditions}

    and g(x) = 55 + 0.01 x ……… (2) {As per given conditions}

    Now, f(x) = g(x)  

    so, 35 + 0.11x = 55 + 0.01x

    ⇒ 0.1x = 20

    x = 200 minutes.

    Therefore, after using 200 minutes the cost of the call will be the same for both the plans. (Answer)
