Linear Programming
The Organic Chemistry Tutor・20 minutes read
Linear programming involves formulating constraints and an objective function to maximize or minimize values, evaluating corner points within the feasible region to determine optimal solutions for sales and profit in scenarios like the carpenter selling tables and rocking chairs. The carpenter should focus on making 20 tables per week to achieve a maximum weekly profit of $1485 by maximizing sales within cost and time constraints.
Insights
- Linear programming involves creating an objective function with three variables and constraints with two variables to find the optimal solution within the feasible region.
- By evaluating the corner points in the feasible region, one can determine the best combination of products to maximize sales and profit, as demonstrated in the case of the carpenter focusing on producing tables to achieve the highest weekly profit.

Optimizing Sales with Linear Programming
- Linear programming involves constraints and an objective function, with the objective typically containing three variables and the constraints having two variables.
- To maximize or minimize the objective function, a graph is plotted in quadrant one, with x and y-intercepts identified for each constraint.
- The region where the shaded areas of the constraints overlap is the feasible region for optimization.
- Corner points within the feasible region are evaluated to find the maximum or minimum value of the objective function.
- A table is created to organize the corner points' coordinates and the corresponding objective function values.
- In a word problem scenario, sales, costs, and time constraints are considered to formulate the objective function and constraints.
- The objective function aims to maximize sales, with the profit being the difference between sales and costs.
- Constraints are set based on cost limitations and time constraints, with the goal of maximizing sales within these constraints.
- A graph is plotted to visualize the feasible region, with corner points representing potential maximum sales values.
- Evaluating the corner points reveals the optimal combination of tables and rocking chairs to maximize weekly sales and determine the maximum profit.

Maximizing Profit Through Table Production
- The carpenter aims to maximize his weekly sales and profit by selling tables and rocking chairs.
- Each table sells for $90, while each rocking chair sells for $180.
- It takes 2 hours to make a table and 5 hours to make a rocking chair.
- The cost to make a table is $15, and the cost to make a rocking chair is $45.
- To maximize sales, the carpenter should focus on making tables, producing a maximum of 20 tables per week, resulting in a maximum weekly sales of $1800 and a maximum weekly profit of $1485.
