Introduction

In the world of business and economics, understanding the relationship between the number of units sold and the resulting profit is crucial for making informed decisions. A company's profit model can be represented by a mathematical function, which can be used to predict and analyze the impact of various factors on the company's revenue. In this article, we will explore how to model a company's profit function based on a given profit model.

Understanding the Profit Model

According to the given profit model, the company has a profit of $0 when 10 units are sold and a maximum profit of $18,050 when 105 units are sold. This information can be used to determine the shape and characteristics of the profit function.

The Nature of the Profit Function

The profit function is a quadratic function, which can be represented by the equation:

p(x) = ax^2 + bx + c

where p(x) is the profit, x is the number of units sold, and a, b, and c are constants.

Determining the Constants

To determine the constants a, b, and c, we can use the given information about the profit model. We know that when x = 10, p(x) = 0, and when x = 105, p(x) = 18,050.

Using the Given Information

We can use the given information to create a system of equations:

a(10)^2 + b(10) + c = 0 a(105)^2 + b(105) + c = 18,050

Solving the System of Equations

To solve the system of equations, we can use substitution or elimination. Let's use substitution.

Substitution Method

Rearranging the first equation, we get:

c = -10a - 10b

Substituting this expression for c into the second equation, we get:

a(105)^2 + b(105) + (-10a - 10b) = 18,050

Simplifying the Equation

Expanding and simplifying the equation, we get:

10,512.5a + 105b - 10a - 10b = 18,050

Combining Like Terms

Combining like terms, we get:

10,502.5a + 95b = 18,050

Dividing by 95

Dividing both sides of the equation by 95, we get:

110.53a + b = 190.53

Solving for a

To solve for a, we can use the fact that when x = 10, p(x) = 0. Substituting x = 10 into the profit function, we get:

0 = 10a + b + c

Substituting c

Substituting c = -10a - 10b into the equation, we get:

0 = 10a + b - 10a - 10b

Simplifying the Equation

Simplifying the equation, we get:

0 = -9b

Solving for b

Solving for b, we get:

b = 0

Substituting b

Substituting b = 0 into the equation 110.53a + b = 190.53, we get:

110.53a = 190.53

Solving for a

Solving for a, we get:

a = 1.73

Finding c

Now that we have found a, we can find c by substituting a into one of the original equations. Let's use the equation c = -10a - 10b.

Substituting a and b

Substituting a = 1.73 and b = 0 into the equation, we get:

c = -10(1.73) - 10(0)

Simplifying the Equation

Simplifying the equation, we get:

c = -17.3

The Profit Function

Now that we have found a, b, and c, we can write the profit function:

p(x) = 1.73x^2 + 0x - 17.3

Simplifying the Function

Simplifying the function, we get:

p(x) = 1.73x^2 - 17.3

The Graph of the Profit Function

The graph of the profit function is a parabola that opens upward. The vertex of the parabola is at x = 52.5, which represents the number of units sold at which the profit is maximized.

Conclusion

In this article, we have modeled a company's profit function based on a given profit model. We have used the given information to determine the constants a, b, and c, and have written the profit function as p(x) = 1.73x^2 - 17.3. The graph of the profit function is a parabola that opens upward, with the vertex at x = 52.5. This information can be used to predict and analyze the impact of various factors on the company's revenue.

Real-World Applications

The profit function can be used in a variety of real-world applications, such as:

Predicting Revenue: The profit function can be used to predict the company's revenue based on the number of units sold.
Analyzing the Impact of Factors: The profit function can be used to analyze the impact of various factors, such as changes in production costs or marketing strategies, on the company's revenue.
Making Informed Decisions: The profit function can be used to make informed decisions about production levels, pricing, and other business strategies.

Limitations

The profit function has several limitations, including:

Assumes a Linear Relationship: The profit function assumes a linear relationship between the number of units sold and the resulting profit, which may not always be the case.
Does Not Account for External Factors: The profit function does not account for external factors, such as changes in market demand or competition, that may impact the company's revenue.
Requires Accurate Data: The profit function requires accurate data about the company's profit model, which may not always be available.

Future Research
