Introduction

In personal finance, it's essential to track and categorize expenses to make informed decisions about budgeting and saving. Alexandra, in this scenario, has recorded her fixed and total expenses for the month. By analyzing these numbers, we can determine her variable expenses, which are essential for understanding her financial situation. In this article, we'll explore the concept of variable expenses and create an equation to represent Alexandra's variable expenses for last month.

Fixed Expenses

Fixed expenses are costs that remain the same over time, such as rent, mortgage, car loan payments, and insurance premiums. These expenses are typically non-negotiable and must be paid regularly. In Alexandra's case, her fixed expenses amount to $\$1,832.76$ .

Total Expenses

Total expenses, on the other hand, include both fixed and variable expenses. Variable expenses, which we'll discuss later, are costs that can vary from month to month, such as groceries, entertainment, and travel expenses. Alexandra's total expenses for the month are $\$4,295.82$ .

Variable Expenses

Variable expenses are costs that can change from month to month, depending on individual circumstances. These expenses are often discretionary and can be adjusted to fit a person's budget. To find Alexandra's variable expenses, we need to subtract her fixed expenses from her total expenses.

Equation for Variable Expenses

Let's denote Alexandra's variable expenses as $v$ . We can create an equation to represent her variable expenses by subtracting her fixed expenses from her total expenses:

$v = \text{Total Expenses} - \text{Fixed Expenses}$

Substituting the given values, we get:

$v = \$4,295.82 - \$1,832.76$

Simplifying the Equation

To simplify the equation, we can perform the subtraction:

$v = \$2,463.06$

This equation represents Alexandra's variable expenses for last month.

Conclusion

In conclusion, understanding variable expenses is crucial for making informed decisions about budgeting and saving. By analyzing Alexandra's fixed and total expenses, we were able to create an equation to represent her variable expenses for last month. This equation can be used to track and manage variable expenses, helping Alexandra make adjustments to her budget as needed.
