With a little practice, you'll be a discount-calculating whiz! Let's jump in and explore how Mariana figures out her cell phone discount.

Breaking Down the Original Price

Before we can calculate the discount, we need to know the original price of the cell phone. Let's say the phone Mariana wants costs $500. This is the original price, the starting point for our calculations. Understanding the original price is crucial because it's the foundation upon which the discount is applied. Think of it as the full cost of the item before any savings are factored in. It's the amount you would pay if there were no discounts or special offers available. So, in Mariana's case, the $500 price tag represents the total cost of the cell phone before any discounts are applied. This initial price sets the stage for determining how much Mariana will save and what her final cost will be. Without knowing the original price, it's impossible to accurately calculate the discount or the final price. Therefore, identifying the original price is always the first step in any discount calculation. Now that we know the original price is $500, we can move on to understanding the discount percentage and how it will affect the final cost. Remember, the original price is the starting point, and the discount will reduce this amount. By clearly understanding the original price, we can easily see how much money Mariana will save and what her ultimate cost will be. This is a critical step in making informed purchasing decisions and ensuring you're getting the best deal possible. So, let's keep the original price of $500 in mind as we explore the discount percentage and how to calculate the final price. This foundation will help us accurately determine Mariana's savings and the ultimate cost of her new cell phone. Knowing the original price is like having the starting point on a map – you need it to figure out the best route to your destination, which in this case is the final price after the discount.

Understanding the Discount Percentage

Next up, we need to understand the discount percentage. Imagine the store is offering a 20% discount on the cell phone. This means Mariana will save 20% of the original price. Discount percentages are a common way for stores to attract customers and offer savings. It's essential to understand what a percentage means in the context of a discount. A discount percentage tells you the portion of the original price that will be deducted. In this case, 20% means that 20 out of every 100 dollars of the original price will be subtracted from the total. So, how do we translate this percentage into a dollar amount? That's where the calculation comes in. To calculate the discount, we need to convert the percentage into a decimal. This is done by dividing the percentage by 100. In our example, 20% becomes 0.20 (20 ÷ 100 = 0.20). This decimal is the key to unlocking the actual dollar amount of the discount. Understanding the discount percentage is also crucial because it allows you to compare different deals and determine which offers the best savings. For example, a 20% discount might sound appealing, but is it better than a $100 off deal? By knowing how to calculate the dollar amount of a percentage discount, you can make an informed decision. So, remember, the discount percentage is just a starting point. We need to convert it into a decimal and then multiply it by the original price to find out how much Mariana will actually save. With this knowledge, you're one step closer to becoming a discount-calculating expert! Stay tuned as we dive into the actual calculation and see how much Mariana will save on her new cell phone.

Calculating the Discount Amount

Now for the fun part: calculating the discount amount! To do this, we multiply the original price ($500) by the discount percentage as a decimal (0.20). So, $500 * 0.20 = $100. This means Mariana will save $100 on the cell phone. Calculating the discount amount is a straightforward process once you have the original price and the discount percentage. As we saw, the formula is simple: Original Price x Discount Percentage (as a decimal) = Discount Amount. This calculation tells you exactly how much money you will save from the original price. In Mariana's case, saving $100 is a significant amount and makes the purchase much more appealing. Understanding how to calculate this amount is crucial because it allows you to see the real value of the discount. Sometimes a percentage can sound impressive, but the actual dollar savings might not be as substantial as you think. By doing the math, you can ensure you're getting a good deal. For example, a 10% discount on a cheaper item might not save you as much as a 20% discount on a slightly more expensive one. By calculating the discount amount, you can compare different offers and choose the one that saves you the most money. Moreover, knowing the discount amount helps you budget for the purchase. You can subtract the discount from the original price to see the final price you will pay, allowing you to plan your finances effectively. So, remember, calculating the discount amount is a critical step in understanding the true value of a discount and making informed purchasing decisions. Now that we know Mariana will save $100, let's move on to calculating the final price she will pay for the cell phone. This is the ultimate goal – to determine the final cost after the discount is applied.

Finding the Final Price

To find the final price, we subtract the discount amount ($100) from the original price ($500). So, $500 - $100 = $400. Mariana will pay $400 for the cell phone after the discount. Calculating the final price is the last step in determining the actual cost of an item after a discount has been applied. It's the moment of truth when you see exactly how much you'll be paying. The formula is simple: Original Price - Discount Amount = Final Price. In Mariana's case, the final price of $400 is a significant saving compared to the original price of $500. Knowing the final price is crucial for several reasons. First, it allows you to compare prices across different stores or brands. You might find that one store offers a higher discount, resulting in a lower final price. By calculating the final price, you can easily see which option is the most budget-friendly. Second, the final price helps you to stay within your budget. If you have a set amount of money you can spend, knowing the final price ensures you don't overspend. This is especially important when making larger purchases, such as a cell phone. Third, the final price gives you a clear picture of the value you are receiving. By knowing the original price and the discount, you can assess whether the final price is worth the product or service you are purchasing. So, calculating the final price is an essential skill for any savvy shopper. It empowers you to make informed decisions, save money, and stay within your budget. Now that we've calculated Mariana's final price, she can confidently purchase her new cell phone knowing she got a great deal. Let's recap the steps we took to understand the entire process.

Real-World Examples and Practice

Let's look at a couple of real-world examples to solidify your understanding. Imagine a store offers 30% off a pair of shoes that cost $80. First, convert 30% to a decimal: 0.30. Then, multiply the original price by the decimal: $80 * 0.30 = $24. This is the discount amount. Finally, subtract the discount from the original price: $80 - $24 = $56. The final price for the shoes is $56. Another example: A laptop is priced at $1200, and there's a 15% discount. Convert 15% to a decimal: 0.15. Multiply the original price by the decimal: $1200 * 0.15 = $180. Subtract the discount from the original price: $1200 - $180 = $1020. The final price for the laptop is $1020. Real-world examples are invaluable for solidifying your understanding of discount calculations. They allow you to apply the concepts you've learned to everyday situations, making the process more tangible and practical. The more examples you work through, the more confident you'll become in your ability to calculate discounts quickly and accurately.

This skill is incredibly useful in everyday life, from shopping for groceries to making larger purchases like electronics or furniture. Furthermore, practicing with real-world examples helps you to identify different types of discounts and how they are applied. You might encounter percentage discounts, fixed-amount discounts, or even more complex scenarios like buy-one-get-one-free offers. By working through these different scenarios, you'll become adept at recognizing the best deals and maximizing your savings. So, take the time to work through as many examples as you can. Look for discounts in your daily life and challenge yourself to calculate the final price. The more you practice, the more confident and skilled you'll become at calculating discounts. This skill will empower you to make smart purchasing decisions and save money in the long run.
