Quadratic equations can be really useful for managing money and budgeting.

For example, when you sell items, you might want to know how much money you can make. You can use a quadratic equation to figure this out. Here’s an example:

$P(x) = -2x^2 + 100x - 150$

In this equation, $P(x)$ shows the profit you make when you sell $x$ items.

Example

• Maximizing Profit:

By finding the highest point on this graph, known as the vertex, you can see how many items to sell to make the most money.

Budgeting

You can also use quadratic equations to predict your costs over time. This helps you understand how you spend your money.

Using this method can help you keep your finances stable and plan for future expenses.
