Daniel's Expenses: How Much Money Is Left?

Hey guys, ever wondered how to manage your salary after expenses? Let's break down a common scenario and learn how to calculate remaining funds. Today, we're diving into a practical math problem involving Daniel's salary and expenses. This is super relevant because understanding personal finance is a key life skill. Whether you're budgeting for groceries, transportation, or even a fun weekend getaway, knowing how to calculate your expenses and remaining balance is essential. So, stick around as we walk through each step, making sure you grasp the concepts clearly. We'll cover everything from fractions to percentages, and by the end, you’ll be a pro at figuring out your own financial situation! Remember, mastering these skills not only helps with everyday budgeting but also sets a solid foundation for future financial planning. Let's get started and unlock the secrets to smart money management!

Understanding the Problem

So, the core of our problem revolves around Daniel's salary, which is R$ 2,400.00. He spends a portion of this on two key areas: food and transportation. To be precise, he spends three-eighths (3/8) of his salary on food and 20% on transportation. The main question we need to answer is: After these expenses, how much money does Daniel have left? This isn't just a simple subtraction problem; we need to calculate each expense individually before we can find the remaining balance. Think of it like piecing together a puzzle – each expense is a piece, and finding the remaining money is the final picture. We need to understand the relationships between fractions, percentages, and the total salary to solve this. It’s like figuring out how much of the pie Daniel ate and how much is left! Before we jump into the calculations, let's make sure we're clear on what each of these terms means in a financial context. This foundational understanding will make the math much easier to follow.

Calculating Food Expenses

Alright, let's tackle the first expense: food. Daniel spends three-eighths of his salary on food, and his salary is R$ 2,400.00. So, we need to calculate what 3/8 of R$ 2,400.00 is. In mathematical terms, this means we're going to multiply the fraction 3/8 by the total salary. To do this, we can set up the equation like this: (3/8) * R$ 2,400.00. Now, before you grab a calculator, let's think about how we can simplify this. One way to approach it is to first divide the total salary by the denominator of the fraction (which is 8) and then multiply the result by the numerator (which is 3). So, we divide R$ 2,400.00 by 8, which gives us R$ 300.00. Then, we multiply R$ 300.00 by 3. This gives us R$ 900.00. Therefore, Daniel spends R$ 900.00 on food. See? It's not as scary as it looks! Breaking it down into smaller steps makes it much easier to manage. Now that we know the food expenses, let's move on to figuring out how much he spends on transportation.

Calculating Transportation Expenses

Okay, now let's figure out Daniel's transportation expenses. He spends 20% of his salary on transportation, and remember, his salary is R$ 2,400.00. To calculate a percentage of a number, we need to convert the percentage into a decimal. To do this, we divide the percentage by 100. So, 20% becomes 20/100, which simplifies to 0.20. Now, we multiply this decimal by Daniel's total salary. Our equation looks like this: 0.20 * R$ 2,400.00. When we multiply these two numbers, we get R$ 480.00. This means Daniel spends R$ 480.00 on transportation. Another way to think about this is that 20% is one-fifth, so we could also divide R$ 2,400.00 by 5 to get the same result. Percentages can seem tricky, but once you understand the conversion to decimals, they become much easier to work with. Now that we've figured out both the food and transportation expenses, we're one step closer to finding out how much money Daniel has left. Let's move on to the final calculation!

Calculating Remaining Balance

Alright, we're in the home stretch! We know that Daniel's salary is R$ 2,400.00. We've also calculated that he spends R$ 900.00 on food and R$ 480.00 on transportation. To find out how much money he has left, we need to subtract these expenses from his total salary. First, let's add up the total expenses: R$ 900.00 (food) + R$ 480.00 (transportation). This gives us a total of R$ 1,380.00. Now, we subtract this total from his salary: R$ 2,400.00 (salary) - R$ 1,380.00 (expenses). When we do the subtraction, we get R$ 1,020.00. So, Daniel has R$ 1,020.00 left after paying for food and transportation. See how breaking the problem down into smaller steps made it much easier to solve? We first calculated the individual expenses and then subtracted the total from the initial salary. This is a great strategy for tackling any math problem, especially when dealing with finances. Now, let's recap the steps we took and highlight the key takeaways.

Final Answer and Explanation

Okay, let's bring it all together and reveal the final answer! After calculating Daniel's food expenses (R$ 900.00) and transportation expenses (R$ 480.00), we subtracted the total expenses (R$ 1,380.00) from his salary (R$ 2,400.00). This left us with R$ 1,020.00. So, the correct answer is that Daniel has R$ 1,020.00 available after these expenses. It's not one of the options provided (a) R$ 1,200.00, b) R$ 1,440.00, c) R$ 1,680.00, or d) R$ 1,800.00), which suggests there might have been a miscalculation in the original options or in our interpretation. However, our step-by-step calculation shows that R$ 1,020.00 is the accurate amount. This highlights the importance of double-checking your work and ensuring each step is correct. When dealing with real-life financial situations, accuracy is crucial! We walked through each step methodically, from calculating fractions and percentages to subtracting expenses from the total salary. This process is a great example of how to approach similar financial problems in your own life. Remember, breaking down complex problems into smaller, manageable steps can make them much easier to solve. Now, let's wrap up with some key takeaways and how you can apply these skills in your daily life. Understanding these concepts can really empower you to manage your finances effectively.
