    Answer:

    I’m assuming we need to find the number of minute she as used. to do that we can right an inequality with m being the number of minutes

    18+0.06m≥88.56

    we then just solve this like we would with any other algebra equation, First we subtract 18 from both sides.

    0.06m≥70.56

    Then we dives by 0.06

    m≥1176

    Rania has used at least 1176 minutes
