    First write the inequality:

    Let w be the number of weeks.  

    632 - 24w >= 200

    -24w >= -432

    w <= 18.  Notice that the relational operator is reversed when dividing by a negative number.

    I hope this is 2nd grade math and you don't want to be a pilot or a doctor:

     632-200=432

    432/24=18 weeks
