    The inequality that represents how much she would save is

    $112 < x

    Here is how to come up with this answer.

    1. Use math to determine the minimum amount she will save (at least).

    0.2 x 140 x 4 = $112

    2. x would represent all the possible amounts Em could save, so anything greater than or equal to $112 is possible.

    You could also write this as x > $112.
