Verified Answer :

  1. 1.5x < = 51
         x < = 51/1.5
         x < = 34

    2. 2.50x < = 20
        x < = 20/2.5
        x < = 8

    3. x/5 < = 4
         x < = 4 5
         x < = 20...the maximum would be $ 20

    4. not sure how to make this into an inequality...it looks like an equation.
       13/(3 1/4) = x
        13 / (13/4) = x
        13
    4/13 = x
         4 = x...she can make 4 batches

    5. cant see all of it....cant see how many pictures she wants framed

    6. 5L < 55
         L < 55/5
         L < 11...

    7. 4h > = 100
        h > = 100/4
        h > = 25 hrs babysitting

    8. x + 125 + 20 < = 180
        x + 145 < = 180
        x < = 180 - 145
        x < = 35 minutes listening to music
