    Answer: it will take 9 weeks for them to have the same amount in their account.

    Step-by-step explanation:

    Let x represent the number if weeks it will take for them to have the same amount in their savings account.

    Bethany has $120 in her savings account and spends $8 a week at the candy store. It means that the amount that she would have in her account after x weeks is

    120 – 8x

    Johnny has $75 in his savings account and spends $3 a week at the candy store. It means that the amount that she would have in her account after x weeks is

    75 – 3x

    For both amounts to be the same, the number of weeks would be

    120 – 8x = 75 – 3x

    – 3x + 8x = 120 – 75

    5x = 45

    x = 45/5

    x = 9
