    64 weeks

    Step-by-step explanation:

    Given that you already have $400 saved and you save $50 per week, in x weeks, you would have saved:

    400 + (50 * x)

    Also, given that Mr Brierley has $2000 in his bank account and he saves $25 per week, in x weeks, he would have:

    2000 + (25 * x)

    You and Mr Brierley would have the same amount of money when:

    400 + (50 * x) = 2000 + (25 * x)

    Solving for number of weeks, x, we have:

    400 + 50x = 2000 + 25x

    Collecting like terms:

    50x - 25x = 2000 - 400

    25x = 1600

    x = 1600 / 25

    x = 64

    Hence, it will take 64 weeks for you and Mr Brierley to have the same amount of money.
