The problem is, I have no clue what the graphs mean. Its different from other inequalities like this.

hi,
 If tanya can  buy the pair of jeans... then she have $84
            tanya earns $7 per hour...
     so...

             84 = 7 x no. hours tanya worked
if the no. of hours is represent by (h). then..
             84 = 7 x h

but the question asks for the inequality..
     but anyway the amount she earn must be above 84 or equal to 84
      which means
                   7h > or = 84

 this is the inequality the for the first part

now...
   if 7h > 84
 then
        7h/7 > 84/7
         h > 12

so.. the graph should include values above 84|dw:1382107910994:dw|
       then ur graph will be..
           |dw:1382108052367:dw|
