Introduction

In the world of business, profit maximization is a crucial aspect of any company's success. It involves identifying the optimal price at which to sell a product or service to maximize revenue and profitability. In this article, we will explore how mathematical modeling can be used to determine the optimal price for selling an item, using the example of two different items sold at the same price.

The Problem

Let's consider two items sold at the same price, denoted by the variable $s$. The profit made on selling the first item is modeled by the polynomial $s^3 - 70s^2 + 1500s - 10,800$, while the profit made on selling the second item is modeled by the polynomial $s^3 - 30s^2 + 450s - 5000$. Our goal is to find the optimal price $s$ at which to sell both items to maximize profit.

Mathematical Modeling

To approach this problem, we can use mathematical modeling to represent the profit functions of both items. Let's start by analyzing the profit function of the first item:

$$P_1(s) = s^3 - 70s^2 + 1500s - 10,800$$

This polynomial represents the profit made on selling the first item at a price $s$. Similarly, the profit function of the second item is:

$$P_2(s) = s^3 - 30s^2 + 450s - 5000$$

Our goal is to find the optimal price $s$ that maximizes the profit made on selling both items.

Optimization Techniques

To find the optimal price $s$, we can use various optimization techniques, such as calculus or numerical methods. Let's use calculus to find the critical points of the profit functions.

Critical Points

To find the critical points of the profit functions, we can take the derivative of each function with respect to $s$ and set it equal to zero:

$$\frac{dP_1(s)}{ds} = 3s^2 - 140s + 1500 = 0$$

$$\frac{dP_2(s)}{ds} = 3s^2 - 60s + 450 = 0$$

Solving these equations, we get:

$$s_1 = 20, s_2 = 25, s_3 = 30$$

These are the critical points of the profit functions.

Second Derivative Test

To determine whether these critical points correspond to a maximum or minimum, we can use the second derivative test. Taking the second derivative of each function, we get:

$$\frac{d^2P_1(s)}{ds^2} = 6s - 140$$

$$\frac{d^2P_2(s)}{ds^2} = 6s - 60$$

Evaluating these expressions at the critical points, we get:

$$\frac{d^2P_1(s)}{ds^2} (s_1) = 20 - 140 = -120 < 0$$

$$\frac{d^2P_2(s)}{ds^2} (s_2) = 25 - 60 = -35 < 0$$

$$\frac{d^2P_1(s)}{ds^2} (s_3) = 30 - 140 = -110 < 0$$

Since the second derivative is negative at all critical points, we can conclude that these points correspond to a maximum.

Conclusion

In this article, we used mathematical modeling to determine the optimal price for selling two items. We represented the profit functions of both items using polynomials and used calculus to find the critical points. We then used the second derivative test to determine whether these critical points correspond to a maximum or minimum. Our results show that the optimal price for selling both items is $s = 20$ for the first item and $s = 25$ for the second item.

Implications for Business

The results of this study have important implications for business. By using mathematical modeling to determine the optimal price for selling an item, companies can maximize their profit and increase their competitiveness in the market. Additionally, this approach can help companies to identify the optimal price for selling multiple items, taking into account the interactions between them.

Future Research Directions

There are several future research directions that can be explored in this area. One possible direction is to extend this study to include more complex profit functions, such as those with multiple variables or non-linear relationships. Another direction is to investigate the use of machine learning algorithms to determine the optimal price for selling an item. Finally, it would be interesting to explore the application of this approach to real-world business problems, such as pricing strategies for companies in different industries.
