Introduction

In the world of business, understanding the concept of equilibrium price and quantity is crucial for making informed decisions. It helps companies determine the optimal price and quantity of their products to maximize profits. In this article, we will delve into the concept of equilibrium price and quantity, and provide a step-by-step guide on how to calculate it using real-world examples.

What is Equilibrium Price and Quantity?

Equilibrium price and quantity refer to the point at which the supply and demand curves intersect. At this point, the quantity of a product that consumers are willing to buy (demand) is equal to the quantity that producers are willing to supply (supply). This is also known as the break-even point, where the revenue from sales equals the cost of production.

Calculating Equilibrium Price and Quantity

To calculate the equilibrium price and quantity, we need to use the following formulas:

Break-even point (x): The point at which the revenue equals the cost of production.
Equilibrium price (p): The price at which the supply and demand curves intersect.
Equilibrium quantity (q): The quantity at which the supply and demand curves intersect.

Step 1: Define the Cost and Revenue Functions

The cost to produce $x$ units of wire is given by the function $C(x) = 50x + 5000$ , while revenue is given by the function $R(x) = 60x$ . We will use these functions to calculate the break-even point.

Step 2: Set Up the Equation

To find the break-even point, we need to set up the equation $R(x) = C(x)$ , where $R(x)$ is the revenue function and $C(x)$ is the cost function.

import sympy as sp
x = sp.symbols('x')
C = 50x + 5000
R = 60x
equation = sp.Eq(R, C)
solution = sp.solve(equation, x)
print(solution)

Step 3: Solve for x

The solution to the equation is $x = 100$ . This means that the break-even point is at $x = 100$ units.

Step 4: Calculate the Equilibrium Price

To calculate the equilibrium price, we need to substitute the value of $x$ into the revenue function.

# Substitute the value of x into the revenue function
equilibrium_price = R.subs(x, 100)
print(equilibrium_price)

Step 5: Calculate the Equilibrium Quantity

To calculate the equilibrium quantity, we need to substitute the value of $x$ into the supply function.

# Substitute the value of x into the supply function
equilibrium_quantity = x.subs(x, 100)
print(equilibrium_quantity)

Conclusion

In conclusion, calculating the equilibrium price and quantity is a crucial step in business decision-making. By using the formulas and steps outlined in this article, companies can determine the optimal price and quantity of their products to maximize profits.
