Maria's Monthly Budget

Maria is creating a budget for her monthly expenses. She spends $300 on rent, $150 on utilities, and $50 on groceries each month. She also saves $100 each month. If she has a total income of $700, how much money does she have left after her expenses and savings?

Let x be the total amount of money Maria has left after her expenses and savings. We can express this with the following equation:

Equation: $$x = 700 - (300 + 150 + 50 + 100)$$
