Abstract:

This project considers a managerial task of analyzing the cost function, the revenue

function and the profit function of the company. The revenue function will be derived from the

demand function; the extrema analysis is performed. The latter includes the location of the

maximum of the profit with the help of the first derivative and refining this with the help of the

second derivative. Additionally, the graphical representation of the revenue, profit and average

cost function is given.

Problem Statement

The aim of this project was to solve a business problem mathematically in a way that it

can be presented to a manager for decision making purposes. MATLAB was used as the tool of

analysis. The manager is specifically presented with the following total cost function;

C(q)=0.8q2+25q+6000

The management has such a function for the cost and it is true for the production of q

units.

From the given total cost function, we can derive the average cost function as follows;

́C(q)=C(q)

q=0.8q2+25q+6000

q

¿0.8q+25+6000

q

Proposed Solution Methodology

A.Develop a 2D plot for demand versus the price:

The first part of this report sought to develop a 2D plot for the demand versus the price.

The MATLAB code used is given below;

>> p=linspace(0,50,500);

>> q=10000-95*p;

>> plot(p,q)
