a      40v + 15d ≤ 175

 

b     40(2) +  15d  ≤ 175

 

       80 +  15d ≤  175    subtract 80 from both sides

 

       15d  ≤   95        divide both sides by 15

 

          d ≤  6 + 1/3      but   d  must be a whole quantity....so.....d  = 6

 

He can buy  - at most - 6 DVDs 

 

 

c    No DVDs..solve this

 

40 v ≤  175      divide both sides by 40

 

v ≤  4 + 3/8...........  ⇒  4  video games

 

 

 

cool cool cool
