    pls explain further so I can understand

    You need to earn half of $128 a year. So, you'll need to earn $64 a year.

    Let x = the amount of money he should deposit. The account earns 1.6% or 0.016.

    Using simple algebra, I set up the equation and solved for x.

    0.016x = 64
    0.016x/0.016 = 64/0.016
    x = $4,000

    Does that help?
