In the realm of business and economics, understanding the concept of marginal profit is crucial for making informed decisions. Marginal profit, in essence, quantifies the change in profit resulting from selling one additional unit of a product or service. For a shop owner whose profit from selling x benches is elegantly described by the function P(x) = 82x + ln(x^4 + 12) dollars, the determination of the marginal profit function P'(x) becomes a pivotal task. This article delves into the process of finding P'(x), elucidating the underlying mathematical principles and showcasing the practical significance of marginal profit analysis.

Decoding the Profit Function: P(x) = 82x + ln(x^4 + 12)

The profit function P(x) = 82x + ln(x^4 + 12) serves as a mathematical model that encapsulates the relationship between the number of benches sold (x) and the total profit earned (P(x)). This function is composed of two distinct components, each contributing uniquely to the overall profit picture. Let's dissect these components to gain a deeper understanding:

  1. The Linear Component: 82x

The term 82x represents a linear relationship between the number of benches sold and the profit generated. The coefficient 82 signifies the profit earned from each bench sold. In simpler terms, for every bench sold, the shop owner gains $82 in profit. This linear component underscores the direct proportionality between sales volume and profit, assuming a constant profit margin per bench.

  1. The Logarithmic Component: ln(x^4 + 12)

The term ln(x^4 + 12) introduces a non-linear element into the profit function. The natural logarithm function, denoted by ln, plays a crucial role in capturing the diminishing returns often encountered in business scenarios. As the number of benches sold (x) increases, the term x^4 grows rapidly. However, the natural logarithm function ln moderates this growth, ensuring that the overall profit does not increase indefinitely at the same rate. This logarithmic component reflects the reality that the marginal profit from selling additional benches may decrease as sales volume increases due to factors such as market saturation or increased production costs. The constant 12 added within the logarithm serves to ensure that the argument of the logarithm remains positive for all non-negative values of x, preventing mathematical undefinedness. This logarithmic component often accounts for factors such as diminishing returns to scale, where the increase in profit from each additional bench sold decreases as the number of benches sold increases. This could be due to various reasons such as increased competition, market saturation, or the need to lower prices to sell more benches.

In essence, the profit function P(x) = 82x + ln(x^4 + 12) elegantly combines a linear component representing the direct profit from each bench sold with a logarithmic component capturing the nuanced effects of diminishing returns. This holistic representation provides a more realistic and comprehensive depiction of the shop owner's profit dynamics.

The Marginal Profit Function: Unveiling P'(x)

The marginal profit function, denoted as P'(x), is the derivative of the profit function P(x) with respect to the number of benches sold (x). Mathematically, the derivative represents the instantaneous rate of change of a function. In the context of marginal profit, P'(x) quantifies the change in profit resulting from selling one additional bench at a specific sales volume (x). It provides a crucial insight into the profitability of selling an extra unit, guiding decisions related to production, pricing, and sales strategies.

To find P'(x), we need to differentiate the profit function P(x) = 82x + ln(x^4 + 12) with respect to x. This involves applying the fundamental principles of calculus, including the power rule and the chain rule.

Differentiation Process: A Step-by-Step Guide

Let's embark on the journey of differentiation, breaking down the process into manageable steps:

  1. Differentiate the Linear Component:

The derivative of 82x with respect to x is simply 82. This is a direct application of the power rule of differentiation, which states that the derivative of ax (where a is a constant) is a.

  1. Differentiate the Logarithmic Component:

The derivative of ln(x^4 + 12) requires the application of the chain rule. The chain rule states that the derivative of a composite function f(g(x)) is f'(g(x)) * g'(x). In this case, f(u) = ln(u) and g(x) = x^4 + 12.

*   The derivative of *ln(u)* with respect to *u* is *1/u*.
*   The derivative of *x^4 + 12* with respect to *x* is *4x^3*. This is another application of the power rule.

Applying the chain rule, the derivative of ln(x^4 + 12) with respect to x is:

(1 / (x^4 + 12)) * (4x^3) = (4x^3) / (x^4 + 12)

  1. Combine the Derivatives:

The marginal profit function P'(x) is the sum of the derivatives of the linear and logarithmic components:

P'(x) = 82 + (4x^3) / (x^4 + 12)

The Result: P'(x) = 82 + (4x^3) / (x^4 + 12)

Therefore, the marginal profit function for the shop owner's bench sales is P'(x) = 82 + (4x^3) / (x^4 + 12). This function provides a valuable tool for analyzing the profitability of selling additional benches at various sales volumes.

Interpreting the Marginal Profit Function: Unlocking Insights

The marginal profit function P'(x) = 82 + (4x^3) / (x^4 + 12) is not merely a mathematical expression; it is a gateway to understanding the economic dynamics of the shop owner's bench sales. By analyzing this function, we can glean valuable insights into the profitability of selling additional benches at different sales volumes.

  1. Marginal Profit at Specific Sales Volumes:

To determine the marginal profit at a specific sales volume, we simply substitute the value of x into the P'(x) function. For instance, if the shop owner is currently selling 10 benches, the marginal profit from selling the 11th bench can be calculated by evaluating P'(10).

P'(10) = 82 + (4 * 10^3) / (10^4 + 12) ≈ 82.399

This result indicates that selling the 11th bench would generate an additional profit of approximately $82.399.

  1. The Impact of Sales Volume on Marginal Profit:

The marginal profit function reveals how the profitability of selling additional benches changes as the sales volume increases. As x increases, the term (4x^3) / (x^4 + 12) decreases. This is because the denominator x^4 + 12 grows much faster than the numerator 4x^3. Consequently, the marginal profit P'(x) decreases as the sales volume x increases.

This phenomenon reflects the principle of diminishing returns, which suggests that the marginal profit from selling additional units eventually decreases as production or sales volume increases. In the context of bench sales, diminishing returns could arise due to factors such as market saturation, increased competition, or the need to lower prices to attract additional customers.

  1. Optimizing Production and Pricing Strategies:

The marginal profit function serves as a crucial tool for optimizing production and pricing strategies. By analyzing P'(x), the shop owner can identify the sales volume at which the marginal profit is maximized. This information can guide decisions regarding production levels, ensuring that the shop owner produces the optimal number of benches to maximize overall profitability.

Furthermore, the marginal profit function can inform pricing strategies. If the marginal profit is high, the shop owner may consider increasing prices, while if the marginal profit is low, they may need to lower prices to stimulate demand.

  1. Decision-Making Scenarios:

Consider the following scenarios:

*   **Scenario 1: Expanding Production**

    If the shop owner is considering expanding production, the marginal profit function can help determine whether the increased production would be profitable. If *P'(x)* is positive and sufficiently high at the new production level, expanding production would likely be a sound decision.

*   **Scenario 2: Pricing Adjustments**

    If the shop owner is contemplating a price change, the marginal profit function can help assess the potential impact on profitability. If lowering the price is expected to increase sales volume significantly, leading to a higher overall profit despite a lower profit margin per bench, it could be a worthwhile strategy.

In essence, the marginal profit function is a versatile tool that empowers the shop owner to make informed decisions, optimize their operations, and enhance their overall profitability.

Conclusion: The Power of Marginal Profit Analysis

The journey of finding the marginal profit function P'(x) = 82 + (4x^3) / (x^4 + 12) for the shop owner's bench sales has unveiled the profound significance of marginal profit analysis. This function, derived through the principles of calculus, provides a powerful lens through which to examine the profitability of selling additional benches at various sales volumes.

By understanding the marginal profit, the shop owner can make informed decisions regarding production levels, pricing strategies, and overall business operations.
