Introduction

In economics, the demand function and production cost are two crucial concepts that help businesses determine their pricing strategies and production levels. The demand function, denoted by $D(p)$ , represents the number of items that will be demanded when the price is $p$ . On the other hand, the production cost, denoted by $C(x)$ , is the cost of producing $x$ items. In this article, we will delve into the mathematical analysis of these two functions and explore how they can be used to determine the cost of production when the price is $p$ .

The Demand Function

The demand function, $D(p)$ , is a mathematical representation of the relationship between the price of a product and the quantity demanded. It is typically represented as a function of the price, $p$ , and can be expressed as:

D(p) = \frac{a}{p} + b

where $a$ and $b$ are constants that depend on the specific product and market conditions.

The demand function can be interpreted as follows:

When the price is high, the quantity demanded is low, and vice versa.
The demand function is downward-sloping, meaning that as the price increases, the quantity demanded decreases.
The demand function is linear, meaning that it can be represented by a straight line.

The Production Cost Function

The production cost function, $C(x)$ , represents the cost of producing $x$ items. It is typically represented as a function of the quantity produced, $x$ , and can be expressed as:

C(x) = mx + k

where $m$ and $k$ are constants that depend on the specific production process and market conditions.

The production cost function can be interpreted as follows:

The production cost is directly proportional to the quantity produced, meaning that as the quantity produced increases, the production cost also increases.
The production cost has a fixed component, $k$ , which represents the minimum cost of production.
The production cost has a variable component, $mx$ , which represents the cost of producing $x$ items.

Determining the Cost of Production

To determine the cost of production when the price is $p$ , we need to find the quantity produced, $x$ , that maximizes the profit. The profit function, $\pi(x)$ , is defined as the difference between the revenue and the production cost:

\pi(x) = R(x) - C(x)

where $R(x)$ is the revenue function, which is equal to the price times the quantity sold:

R(x) = px

Substituting the expressions for $R(x)$ and $C(x)$ , we get:

\pi(x) = px - (mx + k)

To maximize the profit, we need to find the value of $x$ that maximizes the profit function. This can be done by taking the derivative of the profit function with respect to $x$ and setting it equal to zero:

\frac{d\pi(x)}{dx} = p - m = 0

Solving for $x$ , we get:

x = \frac{p}{m}

Substituting this expression for $x$ into the production cost function, we get:

C\left(\frac{p}{m}\right) = \frac{p}{m}m + k = p + k

This expression represents the cost of production when the price is $p$ .

Conclusion

In conclusion, the demand function and production cost are two crucial concepts in economics that help businesses determine their pricing strategies and production levels. The demand function represents the number of items that will be demanded when the price is $p$ , while the production cost represents the cost of producing $x$ items. By analyzing these two functions, we can determine the cost of production when the price is $p$ . This can be done by finding the quantity produced, $x$ , that maximizes the profit, and then substituting this expression into the production cost function.
