  1. 200lbs - 175lbs = 25lbs
    so keith needs to lose 25lbs or more to reach his target weight of 175lbs
    so 25 divided by 2 (Lbs loss a week) = 12.5
    therefore 12.5 weeks will reach his target of 175lbs or 13 weeks to reach 174lbs (which is less, where he wanted to be)

  2. The inequality would be:

    200-2x < 175

    because 200 is his current weight, and x would be the number of weeks it will take to reach his weight. 200 minus the weight per week should equal less than 175. Does this make sense?
