Problem Statement
Our mathematical journey begins with a clear understanding of the problem at hand. In this problem, we are presented with a basket containing a total of 175 fruits. These fruits are categorized into three types: apples, plums, and apricots. The problem provides us with a specific relationship between the number of apples and plums: there are 15 more apples than plums. However, the exact number of each type of fruit is not directly given, and this is what we need to determine. The primary goal is to find out the number of apricots in the basket. To solve this, we will need to use the information provided to set up equations and solve for the unknowns. This involves a process of translating the word problem into mathematical expressions, which is a fundamental skill in algebra. The challenge lies in how to effectively use the given relationship between apples and plums and the total number of fruits to deduce the number of apricots. This problem is a classic example of how real-world scenarios can be modeled mathematically, and it highlights the importance of careful reading and interpretation of the given information. By systematically breaking down the problem and using algebraic techniques, we can find the solution. Let's proceed by defining our variables and setting up the initial equations to represent the information we have.
Defining Variables
To effectively solve this fruit basket problem, we must first translate the given information into a mathematical form. This begins with defining variables to represent the unknown quantities. Let's assign variables to the number of each type of fruit in the basket. We can use 'a' to represent the number of apples, 'p' to represent the number of plums, and 'c' to represent the number of apricots. By using variables, we can create algebraic expressions and equations that will help us find the values we need. This step is crucial because it transforms the word problem into a set of mathematical relationships that can be manipulated and solved. Defining variables is a fundamental technique in algebra and is used in countless problem-solving scenarios. It allows us to move from a descriptive statement to a precise mathematical model. Once we have defined our variables, we can begin to write equations that capture the relationships described in the problem. For example, the total number of fruits in the basket can be expressed as the sum of the number of apples, plums, and apricots. Similarly, the relationship between the number of apples and plums can be written as an equation using the variables 'a' and 'p'. With these variables defined, we are now ready to express the problem mathematically and start the process of solving for the unknowns. Let's move on to setting up the equations that represent the problem's conditions.
Setting Up the Equations
Now that we have defined our variables, the next critical step is to translate the information given in the problem into mathematical equations. This is a crucial skill in problem-solving as it allows us to express the relationships between the unknowns in a precise and actionable form. The first piece of information we have is that the total number of fruits in the basket is 175. This can be expressed as the equation: a + p + c = 175, where 'a' represents the number of apples, 'p' represents the number of plums, and 'c' represents the number of apricots. This equation gives us a fundamental relationship between the three variables. The second key piece of information is that there are 15 more apples than plums. This can be written as the equation: a = p + 15. This equation provides a direct relationship between the number of apples and plums, allowing us to express one in terms of the other. With these two equations, we have a system that we can use to solve for the unknowns. However, we have three variables and only two equations, which means we cannot directly solve for each variable. This is where careful analysis and substitution come into play. We will need to use these equations in combination to find a way to determine the value of 'c', the number of apricots. Setting up these equations is a critical step because it provides the foundation for the algebraic manipulation that will lead us to the solution. Let's proceed by exploring how we can use these equations to solve for the unknowns.
Solving for the Number of Apricots
With our equations established, we can now embark on the process of solving for the number of apricots. The challenge we face is that we have two equations and three unknowns, which means we need to find a way to express one variable in terms of the others and then substitute. Our equations are: 1) a + p + c = 175 2) a = p + 15. The second equation, a = p + 15, gives us a direct way to substitute 'a' in the first equation. By replacing 'a' with 'p + 15' in the first equation, we get: (p + 15) + p + c = 175. This simplifies to: 2p + 15 + c = 175. Now we have an equation with two variables, 'p' and 'c'. Our goal is to isolate 'c', the number of apricots. To do this, we can rearrange the equation to solve for 'c': c = 175 - 2p - 15, which simplifies to: c = 160 - 2p. This equation expresses 'c' in terms of 'p'. However, we still need to find the value of 'p' to determine the exact number of apricots. To find 'p', we need additional information or a constraint. In this type of problem, we can often use the fact that the number of fruits must be a whole number. This constraint, combined with logical reasoning, can help us narrow down the possibilities for 'p'. Let's consider that 'p' must be a positive integer, and 'c' must also be a positive integer. We can test different values of 'p' to see which one yields a valid value for 'c'. This process involves some trial and error, but it's a logical way to approach the problem when we have limited information. By carefully testing values for 'p', we can find the one that gives us a whole number for 'c', which represents the number of apricots. Let's explore this trial-and-error process and see how we can arrive at the solution.
Trial and Error Method
In the absence of a direct algebraic solution, the trial and error method can be a powerful tool, especially when dealing with integer values. We have the equation c = 160 - 2p, which expresses the number of apricots ('c') in terms of the number of plums ('p'). Since the number of fruits must be a whole number, we can systematically try different integer values for 'p' to see which one gives us a valid integer value for 'c'. This method involves making educated guesses and testing them against the given conditions. We know that 'p' must be a positive integer, and 'c' must also be a positive integer. This gives us a range of possible values for 'p' to consider. We can start by trying different values of 'p' and calculating the corresponding 'c' value. If we get a negative value for 'c', it means our 'p' value is too high. If we get a non-integer value for 'c', it means that 'p' is not the correct value. By systematically testing different values, we can narrow down the possibilities and find the correct value for 'p'. For example, if we try p = 50, then c = 160 - 2(50) = 60. This gives us a valid integer value for 'c'. However, we need to also check if this value makes sense in the context of the original problem. We know that a = p + 15, so if p = 50, then a = 50 + 15 = 65. Now we can check if these values satisfy the total number of fruits: a + p + c = 65 + 50 + 60 = 175. This confirms that our values are correct. The trial and error method, when combined with logical reasoning and the constraints of the problem, can be an effective way to find solutions, especially in situations where direct algebraic solutions are not immediately apparent. Let's summarize our findings and state the final answer.
Final Answer
After systematically applying the trial and error method, we have successfully determined the number of apricots in the basket. We found that when we set the number of plums ('p') to 50, we obtained a valid integer value for the number of apricots ('c'). Specifically, using the equation c = 160 - 2p, we calculated c = 160 - 2(50) = 60. This means there are 60 apricots in the basket. To ensure our solution is correct, we also calculated the number of apples ('a') using the equation a = p + 15. With p = 50, we found a = 50 + 15 = 65 apples. Finally, we verified that the total number of fruits adds up to 175: a + p + c = 65 + 50 + 60 = 175. This confirms that our solution satisfies all the conditions of the problem. Therefore, the final answer is that there are 60 apricots in the basket. This problem demonstrates how algebraic thinking, combined with logical deduction and trial and error, can be used to solve real-world scenarios. By carefully setting up equations, using substitution, and applying constraints, we were able to arrive at the correct solution. This process highlights the importance of a systematic approach to problem-solving and the power of mathematical reasoning. The solution not only provides the answer but also reinforces the understanding of the underlying mathematical concepts and techniques.
