In Practice Activity 1 John Works As A Delivery Of E-commerce Products On Weekends And To Organize Their Deliveries Efficiently. He Noticed That Every 3 Houses Visited, One Is Empty And That, Every 5 Houses, One Has A Dog
Introduction
In the world of mathematics, problems often arise from real-world scenarios. These problems require the application of mathematical concepts to find solutions. In this article, we will explore a scenario where John, a delivery person for an e-commerce company, faces a challenge in organizing his deliveries efficiently. We will use mathematical concepts to solve this problem and provide a deeper understanding of the underlying principles.
The Problem
John works as a delivery person for an e-commerce company on weekends. He has to visit multiple houses to deliver products to customers. However, he has noticed that every 3 houses he visits, one is empty, and every 5 houses, one has a dog. This creates a problem for John as he needs to plan his deliveries efficiently to minimize the time spent on empty houses and houses with dogs.
Mathematical Modeling
To solve this problem, we can use mathematical modeling. We can represent the situation using a system of linear equations. Let's assume that John visits a total of N houses. We can represent the number of empty houses as E and the number of houses with dogs as D.
We know that every 3 houses, one is empty, so we can represent this as:
E = (N/3)
Similarly, every 5 houses, one has a dog, so we can represent this as:
D = (N/5)
However, we also know that the total number of houses is the sum of empty houses and houses with dogs, plus the remaining houses that do not fit into either category. We can represent this as:
N = E + D + R
where R is the number of remaining houses.
Solving the System of Equations
We can now solve the system of equations to find the values of E, D, and R. We can start by substituting the expression for E into the equation for N:
N = ((N/3)) + D + R
Simplifying the equation, we get:
N = (N/3) + D + R
Multiplying both sides by 3 to eliminate the fraction, we get:
3N = N + 3D + 3R
Subtracting N from both sides, we get:
2N = 3D + 3R
Now, we can substitute the expression for D into the equation:
2N = 3((N/5)) + 3R
Simplifying the equation, we get:
2N = (3N/5) + 3R
Multiplying both sides by 5 to eliminate the fraction, we get:
10N = 3N + 15R
Subtracting 3N from both sides, we get:
7N = 15R
Now, we can solve for R:
R = (7N/15)
Interpretation of Results
We have now solved the system of equations to find the values of E, D, and R. We can interpret the results as follows:
- The number of empty houses is E = (N/3)
- The number of houses with dogs is D = (N/5)
- The number of remaining houses is R = (7N/15)
Conclusion
In this article, we have used mathematical concepts to solve a real-world problem faced by John, a delivery person for an e-commerce company. We have represented the situation using a system of linear equations and solved the system to find the values of E, D, and R. The results provide a deeper understanding of the underlying principles and can be used to plan deliveries efficiently.

Q&A: Solving Real-World Problems with Mathematical Concepts ===========================================================
Introduction
In our previous article, we explored a scenario where John, a delivery person for an e-commerce company, faced a challenge in organizing his deliveries efficiently. We used mathematical concepts to solve this problem and provide a deeper understanding of the underlying principles. In this article, we will answer some frequently asked questions related to this topic.
Q: What is the main challenge faced by John in organizing his deliveries?
A: The main challenge faced by John is that every 3 houses he visits, one is empty, and every 5 houses, one has a dog. This creates a problem for John as he needs to plan his deliveries efficiently to minimize the time spent on empty houses and houses with dogs.
Q: How did you represent the situation using a system of linear equations?
A: We represented the situation using a system of linear equations by assuming that John visits a total of N houses. We then represented the number of empty houses as E and the number of houses with dogs as D. We used the following equations:
E = (N/3) D = (N/5) N = E + D + R
where R is the number of remaining houses.
Q: How did you solve the system of equations?
A: We solved the system of equations by substituting the expression for E into the equation for N. We then simplified the equation and solved for R.
Q: What is the significance of the number of remaining houses (R)?
A: The number of remaining houses (R) represents the number of houses that do not fit into either the empty house category or the house with a dog category. This is an important consideration for John as he needs to plan his deliveries efficiently to minimize the time spent on these houses.
