The problem centers around a store that offers two types of beverages: cold and hot. Each type has a different price point, and the store's sales data for a specific Saturday provides us with key information to analyze. Let's formally state the problem:
A store sells both cold and hot beverages. Cold beverages (c) are priced at $1.50 each, while hot beverages (h) cost $2.00 each. On Saturday, the total revenue from drink sales was $360. Additionally, the store sold four times as many cold beverages as hot beverages. The primary goal is to determine the number of cold and hot beverages sold on Saturday. This problem is a classic example of a system of equations, where we have two unknowns (c and h) and two pieces of information that can be translated into mathematical equations. Solving this system will give us the exact quantities of each type of beverage sold.
This problem is not just an academic exercise; it mirrors real-world scenarios faced by businesses daily. Retailers need to track sales, understand customer preferences, and manage inventory effectively. By analyzing sales data like this, businesses can make informed decisions about pricing, staffing, and stock levels. For instance, if the store finds that cold beverages are consistently outselling hot beverages by a significant margin, they might consider adjusting their inventory orders or running promotions to balance sales. Furthermore, this type of analysis can help in forecasting future sales trends, allowing the business to prepare for seasonal changes in demand. The problem also highlights the importance of accurate record-keeping and data analysis in business operations. Without reliable sales data, it would be impossible to perform this kind of analysis and gain valuable insights into customer behavior and sales patterns. Thus, this problem serves as a microcosm of the larger challenges and opportunities in the retail industry, where mathematical analysis plays a crucial role in driving success and profitability.
To solve this problem, we need to translate the given information into mathematical equations. This involves identifying the key variables and relationships, and then expressing them in a formal mathematical language. This process is crucial in problem-solving, as it allows us to use algebraic techniques to find the unknown quantities. The ability to set up equations accurately is a fundamental skill in mathematics and has wide-ranging applications in various fields.
First, let's define our variables:
- Let c represent the number of cold beverages sold.
- Let h represent the number of hot beverages sold.
Now, we can use the given information to form two equations. The first piece of information is the total revenue from drink sales, which was $360. We know that each cold beverage costs $1.50 and each hot beverage costs $2.00. Therefore, the total revenue can be expressed as the sum of the revenue from cold beverages and the revenue from hot beverages. This gives us our first equation:
Equation 1: 1.50c + 2.00h = 360
This equation represents the total revenue generated from the sales of cold and hot beverages. The term 1.50c represents the revenue from cold beverages, while 2.00h represents the revenue from hot beverages. The sum of these two terms equals the total revenue of $360.
The second piece of information is that the store sold four times as many cold beverages as hot beverages. This can be directly translated into a relationship between c and h. The number of cold beverages (c) is four times the number of hot beverages (h). This gives us our second equation:
Equation 2: c = 4h
This equation establishes a direct proportionality between the number of cold beverages and hot beverages sold. It indicates that for every hot beverage sold, four cold beverages were sold. These two equations form a system of linear equations, which can be solved to find the values of c and h. The ability to translate real-world information into mathematical equations is a critical skill in problem-solving and allows us to use the power of algebra to find solutions. In this case, we have successfully set up a system of equations that captures the essence of the problem, paving the way for us to find the number of cold and hot beverages sold on Saturday. This process underscores the importance of clear thinking and precise mathematical formulation in tackling real-world problems.
With the equations set up, the next step is to solve them to find the values of c and h. There are several methods to solve a system of equations, including substitution, elimination, and graphical methods. In this case, the substitution method is particularly suitable because we have one equation (c = 4h) that expresses one variable in terms of the other. The ability to choose the most efficient method for solving a system of equations is a valuable skill in mathematics, and understanding the strengths and weaknesses of each method is crucial for effective problem-solving.
The substitution method involves substituting one equation into the other to eliminate one variable. In our case, we can substitute Equation 2 (c = 4h) into Equation 1 (1.50c + 2.00h = 360). This will give us a single equation with only one variable, h, which we can then solve.
Substituting c = 4h into 1.50c + 2.00h = 360, we get:
- 50(4h) + 2.00h = 360
Simplifying this equation, we have:
6h + 2h = 360
Combining like terms, we get:
8h = 360
Now, we can solve for h by dividing both sides of the equation by 8:
h = 360 / 8
h = 45
So, the store sold 45 hot beverages on Saturday. Now that we have the value of h, we can use Equation 2 (c = 4h) to find the value of c:
c = 4 * 45
c = 180
Therefore, the store sold 180 cold beverages on Saturday. We have now successfully solved the system of equations using the substitution method. This process demonstrates the power of algebraic techniques in solving real-world problems. By carefully setting up the equations and applying the appropriate solution method, we were able to determine the exact quantities of cold and hot beverages sold on Saturday. This solution not only answers the specific question posed but also illustrates the broader applicability of mathematical problem-solving in various contexts. The ability to solve systems of equations is a fundamental skill in mathematics and has applications in diverse fields such as engineering, economics, and computer science. This example highlights the importance of mastering this skill for both academic and practical purposes.
After finding the solution, it is crucial to verify its correctness. This step ensures that the values obtained satisfy all the conditions stated in the problem. Verification not only confirms the accuracy of the solution but also reinforces the understanding of the problem and the solution process. This practice is essential in mathematics and other quantitative disciplines, as it helps to catch errors and build confidence in the results. There are several ways to verify a solution, including plugging the values back into the original equations and checking if they hold true.
To verify our solution, we need to check if the values c = 180 and h = 45 satisfy both Equation 1 (1.50c + 2.00h = 360) and Equation 2 (c = 4h).
First, let's check Equation 1:
- 50(180) + 2.00(45) = 270 + 90 = 360
The equation holds true, as the total revenue from 180 cold beverages and 45 hot beverages is indeed $360.
Next, let's check Equation 2:
180 = 4 * 45
180 = 180
This equation also holds true, as the number of cold beverages (180) is four times the number of hot beverages (45). Since both equations are satisfied, we can confidently conclude that our solution is correct. The store sold 180 cold beverages and 45 hot beverages on Saturday. This verification process underscores the importance of double-checking our work to ensure accuracy. In mathematical problem-solving, it is not enough to simply arrive at a solution; we must also verify that the solution is valid and consistent with the given information. This step is particularly crucial in real-world applications, where errors can have significant consequences. By verifying our solution, we not only gain confidence in our results but also develop a more thorough understanding of the problem and the solution process. This practice promotes critical thinking and attention to detail, which are essential skills in mathematics and other fields.
