Represent mathematically the real-life inequality of your choice.

Let's consider a scenario involving a budget for buying items.

Suppose you have a budget of Tshs 10,000 to buy pens and notebooks.
Let $p$ be the cost of one pen (e.g., Tshs 500).
Let $n$ be the cost of one notebook (e.g., Tshs 1,500).
Let $x$ be the number of pens you buy.
Let $y$ be the number of notebooks you buy.
Your total spending must be less than or equal to your budget.

The total cost of $x$ pens is $p \times x$.
The total cost of $y$ notebooks is $n \times y$.
The total spending is $p \times x + n \times y$.
The budget is Tshs 10,000.

So, the inequality is:

Using the example costs:

This inequality represents that the total cost of pens and notebooks must not exceed Tshs 10,000.
