    Charlie has $2700 in his bank account. He spends $150 a week. How many weeks will have passed when Charlie has $600 in his bank account?

    Let w be the weeks that pass. We have the following equation for Charlie's balance:
    2700 - 150w = 600

    To solve for w, we type this equation into our math engine and we get:
    w = 14
