Calculating Investment Returns Type The Correct Answer

Hey guys! Ever stumbled upon those math problems that make you scratch your head and wonder, "How do I even start?" Well, today, we're diving into one of those, but don't worry, we'll break it down together. We're tackling a question about investments and returns, and we're going to use some good ol' math skills to crack it. The key here is to understand the fundamentals of percentages and how they apply to real-world scenarios like savings accounts. So, buckle up, grab your calculators (or your mental math muscles), and let's get started!

Understanding the Investment Scenario

In this mathematical journey, we are presented with a scenario involving David, who makes a savvy investment of $230 in a savings account. This isn't just any savings account, though; it's one that offers a return on investment, specifically a 3% return. Now, what does that even mean? Essentially, the bank is saying, "Hey David, thanks for trusting us with your money. We're going to give you a little extra as a reward!" This "little extra" is the 3% return, and it's calculated based on the initial amount David invested. This concept is crucial in the world of finance, and understanding it can help you make informed decisions about your own money. Think of it like planting a seed; the initial investment is the seed, and the return is the plant that grows from it. The higher the return percentage, the bigger the plant (or the more money!) you'll get back. In this case, David's seed is $230, and we need to figure out how much his plant will grow, considering the 3% return. The challenge is to calculate what value David's investment will reach after this return is applied. This involves a simple yet powerful mathematical concept – calculating percentages. This skill isn't just useful for math problems; it's essential for understanding discounts while shopping, calculating tips at restaurants, and even figuring out interest rates on loans. So, by solving this problem, we're not just getting a correct answer; we're building a real-world skill that can benefit us in numerous situations. Remember, math isn't just about numbers; it's about understanding the world around us. It is a powerful tool that empowers us to make informed decisions and navigate various aspects of our lives, from personal finances to scientific endeavors. So, let’s move on and see how we can calculate David’s investment return, making sure we use numerals instead of words and the “/” symbol for fractions if needed.

Calculating the Return on Investment

Alright, let's get down to the nitty-gritty of calculating David's return on investment. Remember, he invested $230, and the savings account offers a 3% return. So, the big question is: how much is 3% of $230? This is where our percentage prowess comes into play. To calculate a percentage of a number, we need to convert the percentage into a decimal. We do this by dividing the percentage by 100. In this case, 3% becomes 3 / 100, which equals 0.03. Now, we simply multiply this decimal by the original investment amount. So, we have 0.03 multiplied by $230. If you plug that into your calculator (or do it the old-fashioned way!), you'll find that 0.03 * $230 = $6.90. This means that David's investment earned $6.90 in return. But wait, we're not done yet! The question likely asks for the total value of David's investment after the return is applied, not just the return amount itself. To find the total value, we need to add the return to the initial investment. So, we add $6.90 to $230. This gives us $230 + $6.90 = $236.90. Therefore, the total value of David's investment after the 3% return is $236.90. It's like David's money grew a little bit! This is the magic of compound interest, even though we're just looking at a single period in this example. Understanding how these calculations work is incredibly empowering. You can use this same method to calculate interest earned on other investments, figure out discounts at stores, or even calculate tips at restaurants. It’s all about understanding the relationship between percentages, decimals, and the original amount. The ability to calculate percentages is a fundamental skill that transcends the classroom and finds applications in almost every aspect of our lives. From managing personal finances to interpreting statistical data, understanding percentages empowers us to make informed decisions and navigate the complexities of the modern world. So, let’s move forward and delve deeper into how we can accurately represent our answer in the box, keeping in mind the specific instructions provided.

Expressing the Answer Correctly

Okay, we've crunched the numbers and figured out that the total value of David's investment is $236.90. But here's a crucial part of solving math problems: we need to make sure we express our answer in the way the question asks for it. The instructions specifically say, "Type the correct answer in the box. Use numerals instead of words. If necessary, use / for the fraction bar." This means we can't write "two hundred thirty-six dollars and ninety cents." We need to use the numerical representation: 236.90. The instruction to use numerals is straightforward, but it's a common mistake to write out numbers, especially when dealing with significant amounts. Always double-check the instructions to ensure you're following the specified format. The phrase "if necessary, use / for the fraction bar" is also important. In this particular problem, we don't need to use a fraction, as our answer is a decimal. However, if the problem involved a fraction, we would need to use the "/" symbol to represent it. For example, if the answer was one-half, we would write it as 1/2. Understanding this instruction is vital for problems involving ratios, proportions, or any situation where fractional representation is required. It ensures clarity and avoids ambiguity in the answer. So, in this case, we confidently type 236.90 into the box. We've used numerals, and we haven't needed the fraction bar. We've followed the instructions perfectly! This attention to detail is what separates a good problem solver from a great one. It's not just about getting the right answer; it's about presenting it in the correct format. It showcases your understanding of the problem and your ability to communicate your solution effectively. Now that we know how to properly express our answer, let’s briefly recap the steps we’ve taken to solve this problem and reinforce our understanding of the underlying concepts.

Reviewing the Steps and Key Concepts

Alright, let's take a step back and review the journey we've taken to solve this problem. This is a great way to solidify our understanding and make sure we can tackle similar problems in the future. First, we carefully read and understood the scenario: David invested $230 in a savings account with a 3% return. We identified the key information: the initial investment ($230) and the return percentage (3%). Then, we moved on to the calculation phase. We knew that to find the return amount, we needed to calculate 3% of $230. We converted the percentage to a decimal (3% = 0.03) and multiplied it by the initial investment (0.03 * $230 = $6.90). This gave us the amount of the return, which is $6.90. Remember, this is the extra money David earned on his investment. Next, we determined the total value of David's investment by adding the return to the initial investment ($230 + $6.90 = $236.90). This is the final value of David's investment after the return is applied. Finally, and crucially, we focused on expressing the answer correctly. We followed the instructions to use numerals instead of words and to use "/" for fractions if needed. We confidently typed 236.90 into the box, knowing we had followed all the guidelines. Throughout this process, we've reinforced some key mathematical concepts, such as percentages, decimals, and calculating returns on investments. We've also highlighted the importance of carefully reading and following instructions, a skill that's valuable not just in math but in all areas of life. By breaking down the problem into smaller, manageable steps, we made it less intimidating and more approachable. Remember, problem-solving is a process, and each step builds upon the previous one. So, next time you encounter a similar problem, remember these steps, and you'll be well on your way to finding the correct answer.
