We can put this information into two equations:

7 booklets = 140 stamps
3 booklets = 60 stamps

Let us then focus on one equation to find the relationship:

7 booklets = 140 stamps

If we put that into a fraction, we get [tex] \frac{7}{140} [/tex] or [tex] \frac{1}{20} [/tex].

This means that for every booklet, Ashley gets 20 stamps; or rather, each booklet has 20 stamps.

We can then see that this relationship holds true for the second equation as well:

[tex] \frac{3}{60} [/tex] or [tex] \frac{1}{20} [/tex].

To write a general equation for this relationship using p for the number of postage stamps, and b for the number of booklets:

p = 20b

Where b is equal to p.
