    At 50 minutes, the monthly bills will be same.

    Step-by-step explanation:

    Sprint charges;

    Per month fee = $50 = 50*100 = 500 cents

    Charges per minute = 15 cents

    Let,

    x be the minutes.

    S(x) = 500 + 15x

    Verizon charges;

    Per minute charges = 25 cents

    V(x) = 25x

    When the bills will be same, the functions will be equal.

    S(x) = V(X)

    500+15x=25x\\500=25x-15x\\500=10x\\10x=500\\

    Dividing both sides by 10

    \frac{10x}{10}=\frac{500}{10}\\x=50

    At 50 minutes, the monthly bills will be same.
