Application Of The Derivativeafter An Aggressive Mark

Assignment 2 (Application of The Derivative) After an aggressive marketing campaign in the local community, Poe's TV Sales & Repair Co. discovered that their cost can now be modeled by the equation: C(n) = 25n^2 + 150n + 21500, where n represents the number of small screen televisions produced in a particular month.

1. How many small screen televisions must be produced in a month in order to minimize the company's average cost? Show all steps and justify your answer.

2. What is that minimum average cost?

The application of calculus, particularly the derivative, provides a powerful tool for optimizing business functions such as cost minimization. In this context, Poe's TV Sales & Repair Co. seeks to determine the optimal number of small screen televisions to produce in order to minimize the company's average cost, which is crucial for maximizing profitability and competitive advantage. This paper will explore the mathematical approach to solving this problem through deriving the necessary conditions for cost minimization and calculating the minimal average cost based on the given cost function.

The cost function given is C(n) = 25n^2 + 150n + 21500, where n represents the number of televisions produced. To identify the optimal production quantity, it is essential to analyze the average cost per unit, A(n), which is obtained by dividing the total cost C(n) by n:

A(n) = C(n) / n = (25n^2 + 150n + 21500) / n = 25n + 150 + 21500 / n.

The goal is to find the value of n that minimizes A(n). This involves finding the critical points of A(n) by differentiating A(n) with respect to n and setting the derivative equal to zero:

dA/dn = d/dn (25n + 150 + 21500 / n) = 25 - 21500 / n^2.

Setting the derivative equal to zero yields:

25 - 21500 / n^2 = 0,

which simplifies to:

25 = 21500 / n^2.

Multiplying both sides by n^2 gives:

25n^2 = 21500.

Dividing both sides by 25:

n^2 = 21500 / 25 = 860.

Taking the positive square root (since production quantity cannot be negative):

n = √860 ≈ 29.33.

Since production must be an integer, and assuming that fractional production is not feasible, Poe's TV Sales & Repair Co. should produce either 29 or 30 televisions to approach the optimal point. To determine which is more accurate, we analyze the average cost at these two points.

Evaluating A(n) at n=29:

A(29) = 25(29) + 150 + 21500 / 29 ≈ 725 + 150 + 741.38 ≈ 1616.38.

At n=30:

A(30) = 25(30) + 150 + 21500 / 30 ≈ 750 + 150 + 716.67 ≈ 1616.67.

The average cost is slightly lower at n=29, indicating that producing approximately 29 televisions minimizes the average cost.

Finally, to find the minimum average cost, substitute n=29 into A(n):

A(29) ≈ 25(29) + 150 + 21500 / 29 ≈ 725 + 150 + 741.38 ≈ 1616.38.

Therefore, Poe's TV Sales & Repair Co. should produce approximately 29 televisions per month to minimize their average cost, which would be roughly $1,616.38.

In conclusion, the calculus-based optimization approach successfully determines the production quantity that minimizes average costs, thus providing valuable insights for managerial decision-making and strategic planning. The key steps involve deriving the average cost function, computing its derivative, setting it to zero, solving for the critical point, and verifying which quantifies the minimum cost point. This process exemplifies the practical application of derivatives in operational and managerial contexts, enabling businesses to optimize resources efficiently.
