yes

anonymous · Answer

you need solve for n and f?

anonymous · Answer

Yes.  I have to graph the equation and use the graph to determine three different combinations of folders and notebooks that total $12

anonymous · Answer

Ok, give me a minute I have to write on my paper first

anonymous · Answer

subtitution: f=12-n
0.3(12-n)+1.5n=12
3.6-0.3n+1.5n=12
                1.2n= 12- 3.6
                     n=8.4/1.2
      notebooks = 7
subtitution notebooks = 7 find  folders
0.3f+1.5(7)=12
0.3f +10.5 =12
           0.3 f=12-10.5
                 f= 1.5/0.3
     folders  = 5
