Mathematical Problem-Solving: Real-World Applications

2.6. Parcel Capacity Problem

When it comes to solving mathematical problems, understanding the relationship between variables is crucial. In this scenario, an employee at a courier business has a specific capacity to carry parcels in a container. The problem states that if each parcel weighs 300 g, the employee can easily carry 28 parcels at a time. However, the question arises: how many parcels can he carry if each parcel weighs 400 g?

To solve this problem, we need to establish a relationship between the weight of the parcels and the number of parcels the employee can carry. Let's denote the number of parcels as 'n' and the weight of each parcel as 'w'. We are given two scenarios:

Scenario 1: n = 28, w = 300 g
Scenario 2: w = 400 g (new weight)

We can use the concept of proportionality to solve this problem. Since the weight of the parcels is directly proportional to the number of parcels, we can set up a proportion:

n1 / w1 = n2 / w2

where n1 and w1 are the initial number of parcels and weight, and n2 and w2 are the new number of parcels and weight.

Plugging in the values, we get:

28 / 300 = n2 / 400

To solve for n2, we can cross-multiply:

28 × 400 = 300 × n2

11200 = 300n2

Now, divide both sides by 300:

n2 = 11200 / 300

n2 = 37.33

Since the employee cannot carry a fraction of a parcel, we round down to the nearest whole number:

n2 = 37

Therefore, the employee can carry 37 parcels if each parcel weighs 400 g.

2.7. Marcello's Investment Problem

Marcello invests R21,500 at ABC Bank, which offers a certain interest rate. However, the interest rate is not specified. To solve this problem, we need to understand the concept of simple interest.

Simple interest is calculated using the formula:

I = P × r × t

where I is the interest earned, P is the principal amount (initial investment), r is the interest rate, and t is the time period.

However, the interest rate and time period are not provided. To solve this problem, we need to make an assumption or provide additional information.

Let's assume the interest rate is 5% per annum (this is a common interest rate for savings accounts). We also assume the time period is 1 year.

Using the formula, we can calculate the interest earned:

I = 21500 × 0.05 × 1

I = 1075

Now, we can calculate the total amount Marcello will have after 1 year:

Total Amount = Principal + Interest

Total Amount = 21500 + 1075

Total Amount = 22575

Therefore, Marcello will have R22,575 after 1 year.

Real-World Applications of Mathematical Problem-Solving

Mathematical problem-solving has numerous real-world applications. In the context of the parcel capacity problem, understanding the relationship between variables can help businesses optimize their logistics and reduce costs.

In the context of Marcello's investment problem, understanding simple interest can help individuals make informed decisions about their investments and achieve their financial goals.

By applying mathematical concepts to real-world problems, we can develop critical thinking skills, improve our analytical abilities, and make informed decisions.

Conclusion

Mathematical problem-solving is a crucial skill that has numerous real-world applications. By understanding the relationship between variables, we can solve complex problems and make informed decisions.

In this article, we solved two mathematical problems: the parcel capacity problem and Marcello's investment problem. We applied mathematical concepts to real-world scenarios and developed critical thinking skills.

By practicing mathematical problem-solving, we can improve our analytical abilities, develop problem-solving skills, and achieve our goals.
