Marcelo's Math Problem Calculating Total Money And Affordability

Introduction

This math problem presents a relatable scenario involving Marcelo, a young individual, who initially possesses a certain amount of money. Marcelo's kind mother adds to his funds, creating an opportunity for him to purchase an item. The challenge lies in calculating Marcelo's total money after his mother's contribution and then determining which item, from a list of options with varying prices, he can afford exactly. This problem combines basic addition with practical application in a purchasing decision, making it an engaging exercise in mathematical reasoning and financial literacy.

Problem Breakdown

To solve this problem effectively, we need to break it down into two key steps. First, we must calculate Marcelo's total money after his mother's generous gift. This involves a simple addition operation, combining his initial amount with the amount his mother provided. Second, we must compare Marcelo's total money with the prices of the available items – a Nokia phone, a fan, and a watch – to identify which item he can purchase exactly, meaning the item's price matches his total funds precisely. This step involves comparing numerical values and applying logical reasoning to determine affordability.

Step 1: Calculating Marcelo's Total Money

The first critical step in solving this problem is to accurately calculate the total amount of money Marcelo has after receiving his mother's gift. Marcelo initially has 124 units of currency (we'll assume these are pesos, but the specific currency doesn't affect the calculation). His mother then gives him an additional 55 units. To find the total, we need to add these two amounts together. This is a straightforward addition problem: 124 + 55 = ?. Performing this addition, we find that Marcelo has a total of 179 units of currency. This total is the key figure we'll use in the next step to determine what Marcelo can afford.

Step 2: Determining Affordability

Now that we know Marcelo has a total of 179 units of currency, we can move on to the crucial step of determining which item he can afford to buy. The problem presents three options: a Nokia phone priced at 124 units, a fan priced at 256 units, and a watch priced at 179 units. To determine affordability, we need to compare Marcelo's total money (179 units) with the price of each item. He can only purchase an item if its price is less than or equal to the amount of money he has. Furthermore, the problem specifies that Marcelo has exactly enough money to buy one of the items, meaning the price of the item must match his total funds precisely.

Let's analyze each item individually:

• Nokia Phone: The Nokia phone costs 124 units. Marcelo has 179 units. Since 124 is less than 179, Marcelo could afford the phone. However, he would have money left over, so this doesn't fit the condition of having exactly enough money.
• Fan: The fan costs 256 units. Marcelo has 179 units. Since 256 is greater than 179, Marcelo cannot afford the fan. He does not have enough money to make this purchase.
• Watch: The watch costs 179 units. Marcelo has 179 units. Since 179 is equal to 179, Marcelo has exactly enough money to buy the watch. This perfectly matches the problem's condition.

Solution

Based on our calculations and comparisons, we can confidently conclude that Marcelo has exactly enough money to purchase the watch. The watch costs 179 units, which is precisely the amount of money Marcelo has after his mother's generous gift. Therefore, the answer to the problem is the watch.

Conclusion

This problem beautifully illustrates the practical application of basic arithmetic in everyday financial decisions. By combining addition to calculate total funds with comparative analysis to determine affordability, we successfully identified the item Marcelo could purchase. This exercise not only reinforces mathematical skills but also promotes financial literacy by demonstrating how to manage money and make informed purchasing choices. The problem highlights the importance of careful calculation and comparison when making spending decisions, a valuable lesson for individuals of all ages. Remember, understanding your finances is crucial for making smart choices!
