Decoding Discounts How To Calculate Savings On A Game

Hey guys! Ever stumbled upon a fantastic deal while shopping and had to do some quick math to figure out the final price? Well, let's dive into a scenario just like that! Imagine our friend João is out shopping and spots a game he's been eyeing. It's originally priced at R$ 200,00, but guess what? There's a sweet 15% discount on it! Now, the big questions are: How much money does João save with this discount, and what will he actually pay for the game after the discount is applied?

Understanding the Discount Calculation

Alright, let's break this down step by step so we can all follow along. The most important thing in discount calculation is to understand the percentage. What exactly does a 15% discount mean? It means that for every R$ 100,00, João gets to subtract R$ 15,00 from the original price. Pretty cool, right? So, how do we figure out the total discount amount for a R$ 200,00 game? There are a couple of ways we can tackle this.

Method 1: The Direct Percentage Calculation

The first method involves directly calculating 15% of R$ 200,00. To do this, we convert the percentage into a decimal. Remember, a percentage is just a fraction out of 100, so 15% is the same as 15/100, which equals 0.15 in decimal form. Now, we simply multiply the original price by this decimal:

Discount Amount = 0. 15 * R$ 200,00 = R$ 30,00

So, the discount amount is R$ 30,00! That's a nice chunk of change saved right there.

Method 2: The Proportion Method

Another way to think about this is using proportions. We know that 15% of the total price (R$ 200,00) is equal to the discount amount. We can set up a proportion like this:

15 / 100 = Discount Amount / R$ 200,00

To solve for the Discount Amount, we can cross-multiply:

100 * Discount Amount = 15 * R$ 200,00

100 * Discount Amount = R$ 3000,00

Now, divide both sides by 100:

Discount Amount = R$ 3000,00 / 100 = R$ 30,00

Guess what? We arrived at the same answer! Both methods confirm that the discount amount is indeed R$ 30,00.

Calculating the Final Price

Now that we know the discount amount, figuring out the final price is a piece of cake. We simply subtract the discount from the original price:

Final Price = Original Price - Discount Amount

Final Price = R$ 200,00 - R$ 30,00 = R$ 170,00

So, after applying the 15% discount, João will pay R$ 170,00 for the game.

The Answer

Based on our calculations, the correct answer is:

• Discount: R$ 30,00
• Final Price: R$ 170,00

Why This Matters

Understanding percentage discounts is super practical in everyday life. Whether you're shopping for clothes, electronics, or even groceries, you'll often encounter discounts. Being able to quickly calculate these discounts helps you make informed decisions and save money. Plus, it's a great way to flex those math muscles!

Let's Practice!

Now that we've cracked this problem, let's think about other scenarios. What if the discount was 20%? Or what if the game cost R$ 250,00? Try working through these scenarios to solidify your understanding of percentage discounts. Remember, practice makes perfect!

Conclusion

So, there you have it! We've successfully helped João figure out his discount and the final price of the game. By understanding the concept of percentages and how to apply them, you can become a savvy shopper and make the most of those sweet deals. Keep practicing, and you'll be a discount-calculating pro in no time!

Let's delve into a common yet crucial aspect of everyday life: calculating discounts. Imagine our friend João is on a shopping spree and stumbles upon an enticing offer: a 15% discount on a game originally priced at R$ 200.00. This scenario presents a perfect opportunity to explore the practical application of percentages and how they impact our purchasing decisions. To truly grasp the significance of this situation, we need to dissect it methodically. Understanding discounts isn't just about saving money; it's about making informed choices, budgeting effectively, and appreciating the true value of a product. So, let's embark on this mathematical journey together, unraveling the intricacies of discounts and empowering ourselves to become savvy shoppers.

The Core Question Breaking Down the Problem

The central question here is twofold: First, we need to determine the exact amount of the discount João receives. This involves translating the percentage into a monetary value, providing a tangible representation of the savings. Second, we must calculate the final price João will pay after the discount is applied. This final price reflects the actual cost of the game and is essential for budgeting and comparing prices. To address these questions effectively, we'll explore various methods of calculation, ensuring a comprehensive understanding of the process. Think of this as equipping ourselves with the tools to navigate the world of sales and promotions, turning discounts from abstract figures into concrete savings.

Deciphering Percentages The Foundation of Discounts

Before we jump into the calculations, let's revisit the fundamental concept of percentages. The word “percent” comes from the Latin “per centum,” meaning “out of one hundred.” Therefore, a percentage is essentially a fraction with a denominator of 100. A 15% discount, in this case, signifies that for every R$ 100.00 of the original price, R$ 15.00 is deducted. This understanding is crucial for converting percentages into usable numbers for calculations. Think of it like translating a language; we need to understand the vocabulary (percentages) to interpret the message (the discount value). This foundational knowledge empowers us to tackle more complex discount scenarios with confidence.

Method 1 Direct Percentage Calculation The Straightforward Approach

The most direct method for calculating the discount amount involves converting the percentage into a decimal and then multiplying it by the original price. This approach is efficient and widely applicable. To convert 15% into a decimal, we divide it by 100, resulting in 0.15. We then multiply this decimal by the original price of the game (R$ 200.00). This method is akin to using a formula; we plug in the values and get the answer. It's a reliable technique that simplifies the calculation process. Let's see how it works in practice:

Discount Amount = 0. 15 * R$ 200.00 = R$ 30.00

As we can see, the direct percentage calculation reveals that João will receive a discount of R$ 30.00. This method provides a clear and concise way to determine the monetary value of the discount, making it a valuable tool for any shopper.

Method 2 The Power of Proportions An Alternative Perspective

Another effective method for calculating discounts involves using proportions. This approach highlights the relationship between the percentage, the discount amount, and the original price. A proportion is an equation that states that two ratios are equal. In this context, we can set up a proportion that equates the ratio of the discount percentage to 100 with the ratio of the discount amount to the original price. This method provides a different way of thinking about the problem, appealing to those who prefer visual or relational approaches. It's like looking at the same landscape from a different vantage point, gaining a new appreciation for its features.

The proportion can be expressed as follows:

15 / 100 = Discount Amount / R$ 200.00

To solve for the Discount Amount, we can cross-multiply, resulting in:

100 * Discount Amount = 15 * R$ 200.00

Simplifying the equation, we get:

100 * Discount Amount = R$ 3000.00

Dividing both sides by 100, we find:

Discount Amount = R$ 30.00

This confirms that the discount amount is R$ 30.00, aligning with the result obtained using the direct percentage calculation. The proportion method offers a valuable alternative, reinforcing the understanding of the relationships between the different elements of a discount.

Calculating the Final Price The Last Step

Once we've determined the discount amount, calculating the final price is a straightforward process. We simply subtract the discount from the original price. This final price represents the actual cost João will incur for the game, providing a clear picture of the financial impact of the discount. It's the bottom line, the number that truly matters when making a purchasing decision. The formula is:

Final Price = Original Price - Discount Amount

In João's case:

Final Price = R$ 200.00 - R$ 30.00 = R$ 170.00

Therefore, after applying the 15% discount, João will pay R$ 170.00 for the game. This final price is the result of our calculations, highlighting the power of understanding discounts and their impact on our wallets.

The Grand Reveal Answering the Initial Questions

Now, let's revisit the questions we posed at the beginning of this exploration: What is the discount amount, and what is the final price? Through our calculations, we've definitively answered these questions:

• Discount Amount: R$ 30.00
• Final Price: R$ 170.00

These answers provide a clear and concise summary of the financial impact of the 15% discount on the game. João saves R$ 30.00 and ultimately pays R$ 170.00. This resolution underscores the importance of understanding discounts and their practical application in everyday shopping scenarios.

Real-World Significance Beyond the Game

The ability to calculate discounts extends far beyond the scenario of buying a game. It's a crucial skill for budgeting, comparing prices, and making informed purchasing decisions in various contexts, from grocery shopping to buying electronics. Imagine you're comparing two laptops, one with a 10% discount and another with a 15% discount. By calculating the final prices, you can determine which laptop offers the better value. This skill empowers you to be a savvy consumer, ensuring you get the most for your money. It's not just about saving money; it's about making smart financial choices.

Practice Makes Perfect Sharpening Your Skills

To solidify your understanding of discount calculations, let's consider some additional scenarios: What if the game had a 20% discount? Or what if the original price was R$ 250.00? Working through these examples will reinforce your skills and build your confidence in tackling real-world discount situations. Think of it like learning a musical instrument; the more you practice, the more proficient you become. The same applies to mathematical skills; the more you apply them, the more comfortable and confident you'll be in using them.
