Understanding these payment options is crucial for making informed financial decisions. We will break down the problem step by step, ensuring clarity and a thorough understanding of the solutions. The core of this problem lies in the application of basic arithmetic operations to real-life financial scenarios. By exploring this, we can appreciate the practical relevance of mathematical skills in everyday situations. This article aims not only to solve the problem at hand but also to highlight the importance of financial literacy and the ability to perform simple calculations to manage personal finances effectively. Let's begin by dissecting the first part of the problem, which involves determining the operation needed to calculate Janaína's payment in installments.

Determining the Operation for Installment Payments

The first part of our problem requires us to identify the mathematical operation needed to determine how much Janaína will pay if she opts for a payment plan of five equal installments without any interest. To solve this, we need to understand the basic principles of division. Division is the mathematical operation that allows us to split a whole into equal parts. In this context, the 'whole' is the total amount Janaína needs to pay, and the 'equal parts' are the five installments she will be making. Therefore, the operation required is division. We need to divide the total amount by the number of installments to find the value of each installment. This is a fundamental concept in arithmetic and is widely used in everyday financial calculations. The key here is to recognize that dividing the total cost by the number of installments provides the cost per installment. This is a straightforward application of division and is crucial for budgeting and financial planning. Furthermore, understanding this operation helps in comparing different payment options and choosing the most suitable one. For instance, if Janaína were to compare a three-installment plan with a five-installment plan, she could easily calculate the amount per installment for each option and make an informed decision based on her financial capacity. The ability to perform such calculations is an essential skill in managing personal finances effectively. Now that we have identified the operation, let's move on to the next part of the problem, which involves solving this operation to determine the total amount to be paid per installment.

Solving the Division and Determining the Total Payment

Now that we've established that division is the necessary operation to calculate the amount of each installment, let's assume the total amount Janaína needs to pay is R$ 2500. To find out the value of each of the five equal installments, we will divide the total amount (R$ 2500) by the number of installments (5). The calculation is as follows: R$ 2500 ÷ 5 = R$ 500. This means that each installment will be R$ 500. This simple division allows us to break down a larger payment into smaller, more manageable amounts. Understanding this calculation is essential for budgeting and financial planning. By knowing the exact amount of each installment, Janaína can better manage her expenses and ensure she has enough funds to cover the payments. Moreover, this calculation highlights the practical application of division in real-world scenarios. It demonstrates how a basic mathematical operation can help in making informed financial decisions. In this case, Janaína can now clearly see that opting for the five-installment plan will require her to pay R$ 500 each time. This clarity is crucial for financial stability and peace of mind. Let's now consider the next part of the problem, which involves exploring the implications of choosing to pay upfront with a discount. This will further illustrate the importance of understanding different payment options and their financial impacts.

Analyzing the Upfront Payment Option and Discount

The final part of our problem involves analyzing the scenario where Janaína opts for an upfront payment and receives a discount. Let's assume Janaína is offered a 10% discount if she pays the entire amount of R$ 2500 upfront. To determine how much she will pay with the discount, we need to calculate 10% of R$ 2500 and then subtract that amount from the original price. First, we calculate 10% of R$ 2500: (10/100) * R$ 2500 = R$ 250. This means the discount amount is R$ 250. Next, we subtract the discount from the original price: R$ 2500 - R$ 250 = R$ 2250. Therefore, if Janaína chooses to pay upfront with the 10% discount, she will pay R$ 2250. This calculation demonstrates the financial benefit of availing discounts whenever possible. Understanding percentages and discounts is a crucial aspect of financial literacy. It allows individuals to make informed decisions about their purchases and save money. In this scenario, Janaína saves R$ 250 by choosing the upfront payment option. This is a significant saving and highlights the importance of considering all available payment options before making a decision. Furthermore, this analysis underscores the value of being able to perform basic percentage calculations. The ability to calculate discounts, taxes, and interest rates is essential for managing personal finances effectively. By understanding these concepts, individuals can make smarter financial choices and maximize their savings. Now, let's summarize the entire problem and the solutions we have derived.

Conclusion: Summarizing Janaína's Payment Options

In conclusion, we have thoroughly analyzed Janaína's payment options, breaking down each scenario with clear mathematical calculations. We determined that to calculate the amount of each installment in a five-payment plan, the operation required is division. By dividing the total amount of R$ 2500 by 5, we found that each installment would be R$ 500. This installment plan provides a structured way for Janaína to manage her payments over time. Understanding this calculation helps Janaína budget effectively and ensures she can meet her financial obligations without strain. Furthermore, we explored the option of an upfront payment with a 10% discount. By calculating 10% of R$ 2500 and subtracting it from the original amount, we found that Janaína would pay R$ 2250 if she chose to pay upfront. This upfront payment option offers a significant saving of R$ 250 compared to the installment plan. The analysis highlights the importance of considering all available payment options and choosing the one that best suits her financial situation. Ultimately, the decision of whether to pay in installments or upfront depends on Janaína's financial capabilities and preferences. If she has the funds available, the upfront payment with a discount is the more economical choice. However, if she prefers to spread out the payments over time, the installment plan provides a manageable alternative. This problem underscores the practical application of basic mathematical operations in everyday financial decision-making. By understanding these concepts, individuals can make informed choices and effectively manage their personal finances.
