The number of stamps and the cost are illustrations of unit rates

40 stamps would cost $22

The cost of 15 postage stamps is $8.25

Start by calculating the unit rate of the stamps.

[tex]Unit = \frac{8.25}{15}[/tex]

[tex]Unit = 0.55[/tex]

So, the number of stamps for $22 is calculated by dividing $22 by the unit rate.

So, we have:

[tex]Number=\frac{22}{0.55}[/tex]

[tex]Number=40[/tex]

Hence, 40 stamps would cost $22
