Equation For Cost Of 7 Hats And 3 Scarves
In the realm of mathematical problem-solving, we often encounter scenarios that require us to translate real-world situations into symbolic representations. Let's embark on a journey to decipher a cost-related puzzle involving hats and scarves, transforming the given information into a concise mathematical equation. Our main goal here is to figure out how to write an equation that shows the total cost of hats and scarves based on what we know. This involves turning the words of the problem into math symbols and numbers, which is a key skill in mathematics and helps in solving real-life financial questions.
The essence of our task lies in capturing the relationship between the quantities and prices of these items. The problem presents us with a specific scenario: the combined cost of 7 hats and 3 scarves amounts to . To effectively represent this information, we introduce variables to denote the unknown costs – 'x' for the cost of a hat and 'y' for the cost of a scarf, both measured in pounds. This is a standard approach in algebra, where we use letters to represent amounts we don't know yet. By doing this, we can start to build an equation that models the situation described.
Now, let's meticulously translate the verbal statement into a mathematical equation. We know that the total cost is the sum of the costs of the individual items. Since we have 7 hats, each costing 'x' pounds, their combined cost would be 7 times 'x', or 7x. Similarly, for the 3 scarves, each priced at 'y' pounds, the total cost is 3 times 'y', or 3y. The problem states that the total cost of these hats and scarves together is . Thus, we can express this combined cost as the sum of the individual costs, equating it to the given total. This step is crucial because it bridges the gap between the real-world scenario and its mathematical representation.
Therefore, the equation that accurately represents the given information is 7x + 3y = 124. This equation succinctly captures the relationship between the number of hats and scarves, their respective costs, and the overall expenditure. This equation is a linear equation, which is a fundamental concept in algebra. It tells us that if we know the cost of a hat, we can figure out the cost of a scarf, and vice versa, assuming the total cost remains the same. Understanding how to form such equations is vital for anyone looking to apply mathematical principles to practical situations, whether in business, personal finance, or academic studies. The ability to convert real-world problems into mathematical equations is a powerful tool for analysis and problem-solving.
Before diving into the equation itself, it's crucial to understand the role of variables in translating real-world scenarios into mathematical language. In this particular problem, we're dealing with the costs of two distinct items: hats and scarves. To effectively represent these costs, we introduce variables – symbolic placeholders that allow us to express unknown quantities in a concise and manageable way. The selection of appropriate variables is a foundational step in the algebraic process, paving the way for the formulation of equations that accurately mirror the given information. This approach is a cornerstone of algebra, allowing us to handle unknowns systematically and logically. Using variables, we can manipulate and solve problems that would otherwise be too complex to handle directly.
The problem explicitly defines the variables for us: 'x' represents the cost of a hat, measured in pounds, and 'y' represents the cost of a scarf, also in pounds. This clear definition is essential for maintaining clarity and consistency throughout the problem-solving process. Without a precise understanding of what each variable signifies, the equation we construct would lack meaning and practical application. The use of 'x' and 'y' as variables is a common convention in algebra, but the key is to always define them clearly in the context of the problem. This ensures that anyone reading the solution can understand exactly what each symbol represents.
By assigning 'x' and 'y' to the costs of hats and scarves, respectively, we create a symbolic framework that enables us to manipulate these unknowns algebraically. This is a fundamental principle of algebra: to use symbols to represent quantities that are not immediately known. This allows us to form relationships and equations that can be solved to find the values of these unknowns. The process of defining variables is not just about assigning symbols; it's about setting up a system that allows for logical and mathematical exploration of the problem. It transforms a word problem into a format that can be tackled using algebraic techniques.
The choice of variables is also strategic. Using 'x' and 'y' provides a direct and intuitive link to the items they represent. This helps in keeping the problem organized and makes it easier to track the relationships between the quantities. For example, when we see '7x' in the equation, we immediately understand that it refers to the total cost of 7 hats, each costing 'x' pounds. This direct correspondence between the symbols and the real-world items is crucial for both understanding and solving the problem effectively. Thus, the careful definition and application of variables are indispensable tools in our mathematical toolkit, allowing us to navigate complex problems with clarity and precision.
Now that we have our variables defined, the next crucial step is to translate the verbal information provided in the problem into a mathematical equation. This process involves carefully dissecting the problem statement, identifying the key relationships, and expressing them using mathematical symbols and operations. The ability to translate words into equations is a cornerstone of mathematical problem-solving, allowing us to bridge the gap between real-world scenarios and abstract mathematical representations. This is not just about plugging in numbers; it's about understanding the underlying structure of the problem and expressing it in a form that can be mathematically manipulated.
The problem states that the cost of 7 hats and 3 scarves is . To construct the equation, we need to break down this statement into its constituent parts. We know that the cost of one hat is represented by 'x', so the cost of 7 hats would be 7 times 'x', which we write as 7x. Similarly, the cost of one scarf is represented by 'y', so the cost of 3 scarves would be 3 times 'y', or 3y. The word "and" in the problem suggests addition, as we are combining the costs of the hats and scarves. Therefore, the total cost of 7 hats and 3 scarves can be expressed as the sum of 7x and 3y. This is a critical step in transforming the word problem into a mathematical expression.
The problem also states that this total cost is equal to . The word "is" often signifies equality in mathematical problems. Thus, we can set the expression we derived (7x + 3y) equal to 124. This gives us the equation 7x + 3y = 124. This equation is the mathematical representation of the problem statement, capturing the relationship between the number of hats, the number of scarves, their respective costs, and the total expenditure. The equation is a concise and precise way to express the information given in the problem.
This equation is a linear equation, and it represents a relationship between two variables. It tells us that there are multiple possible solutions for the values of 'x' and 'y' that would satisfy this equation. In other words, there are various combinations of hat and scarf prices that would result in a total cost of $£124. Solving this equation, often with additional information or constraints, would allow us to determine specific values for the cost of a hat and the cost of a scarf. The process of constructing this equation is a fundamental skill in algebra, essential for tackling a wide range of problems involving quantities, costs, and relationships. It demonstrates the power of mathematical notation to simplify and solve complex scenarios.
Having meticulously translated the problem's conditions into mathematical language, we arrive at the equation 7x + 3y = 124.

It allows us to see the mathematical structure of the problem and to apply algebraic techniques to find solutions.
This equation is a linear equation in two variables, 'x' and 'y'. It signifies that the sum of 7 times the cost of a hat (7x) and 3 times the cost of a scarf (3y) is equal to $£124. The equation is a compact way to represent the total cost in terms of the individual item costs. The linearity of the equation implies that the relationship between the costs is constant; for each increase in the cost of a hat, there is a corresponding decrease in the possible cost of a scarf, and vice versa, to maintain the total cost of $£124. This is a fundamental characteristic of linear equations and makes them particularly useful for modeling real-world situations where relationships are proportional.
The equation 7x + 3y = 124 provides a starting point for further analysis. While it doesn't give us a unique solution for 'x' and 'y' (since there are infinitely many pairs of values that could satisfy the equation), it does provide a constraint that the costs must adhere to. To find specific values for 'x' and 'y', we would need additional information, such as another equation relating the costs or a specific value for one of the variables. This is a common situation in algebraic problem-solving, where a single equation often represents a family of possible solutions.
In essence, the equation 7x + 3y = 124 serves as a mathematical model of the given situation. It captures the essential elements of the problem – the number of items, their costs, and the total expenditure – in a form that is amenable to algebraic manipulation. This equation is a clear and precise representation of the problem, allowing us to explore the relationships between the variables and to potentially find solutions. It exemplifies the power of mathematical notation to simplify and formalize real-world problems, making them more accessible to analysis and solution.

The equation is a tool that can be used to answer a variety of questions, and exploring these questions can lead to a more comprehensive understanding of the problem.
For instance, we can use this equation to explore different possible costs for the hats and scarves. If we were to assume a specific cost for a hat (x), we could substitute that value into the equation and solve for the cost of a scarf (y). Conversely, if we knew the cost of a scarf, we could find the corresponding cost of a hat. This type of analysis allows us to understand the trade-offs between the costs of the two items. For example, if hats are expensive, scarves must be cheaper to keep the total cost at $£124, and vice versa. This kind of scenario planning is a valuable application of the equation.
Furthermore, the equation can be used to answer questions about affordability and budgeting. If a customer has a budget of $£124 and wants to buy 7 hats, the equation can help determine the maximum price they can afford for each scarf.
