Optimizing Weekly Profit in Production

This section discusses the application of the modified secant method to optimize the weekly profit for a production process. The scenario involves calculating the optimal quantity of product to maximize profit, given cost and revenue functions.

  • Weekly Cost Function: The cost to produce x kilograms is given by: where 50 is a fixed cost and 2.5 is the variable cost per kilogram.

  • Weekly Revenue Function: The revenue from selling x kilograms is: where 3 is the price per kilogram and represents additional revenue dependent on quantity.

  • Weekly Profit Function: The profit is the difference between revenue and cost: Simplified:

  • Optimization Objective: Find the value of x that maximizes weekly profit.

Secant Method for Root Finding

The secant method is a numerical technique used to find roots of equations, often applied to optimization problems where the derivative of the profit function is set to zero.

  • Derivative of Profit Function: Set to find the maximum.

  • Secant Method Iteration: where is the derivative of the profit function.

  • Iteration Table: The table shows the iterative process for finding the optimal x:
