$12=0.3f+1.5n$

All you need to do is pick three values for n, say, and obtain the corresponding f's from your equation/graph. For example, if you choose 2 notebooks, then n=2 and you have to find f:$12=0.3f+1.5 \times 2 \rightarrow 9=0.3f \rightarrow f=9/0.3=30$i.e. 30 folders can be bought with the remaining money. Hope it helps...

For the example equation 12=0.3f+1.5 x 2, where does the 9 come from? I've been trying to do the calculations and I can't figure it out.
