    Your link is broken. I presume it is an attempt at a solution. Can you type it out?

    Re: Creating expression with written description

    $J =t$

    $W=4+t$

    $D=t-5$

    Since $t-5<t<t+4$

    So, $t-5<t+4$

    Hi Dan,

    Your presumption is correct.

    Here are the four options:

    A) 4 + t
    ------
    5 - t

    B) t + 4
    ------
    t - 5

    C) t - 4
    -----
    t - 5

    D) 4 + t
    -----
    5 + t

    Thank you deesuwalka ; I suppose your response is equivalent to option B
