$M + n \le 26$

#### Explanation:

Sum tells us we are adding.
The total can be 26, or less than 26

$M + n \le 26$

Because we are dealing with an inequality, there are many possible solutions.

If the sum was exactly 26, we could show all the possible combinations on a graph.

The intercepts would be $\left(26 , 0\right) \mathmr{and} \left(0 , 26\right)$

The shaded area represents the possible solutions, but note that only positive whole numbers can be used, because we are dealing with a physical quantity of the number of stamps.
