Golden Harvest Foods makes jumbo biscuits and regular biscuits. The oven can cook at most 200 biscuits per day. Each jumbo biscuit requires 2 oz of flour, each regular biscuit requires 1 oz of flour, and there are 300 oz of flour available. The income from each jumbo biscuit is $\$ 0.10$ and from each regular biscuit is $\$ 0.08 .$ How many of each size biscuit should be made in order to maximize income? What is the maximum income?

Key Concepts

Graphical Method

The graphical method is a technique used to solve linear programming problems involving two variables by plotting the constraint inequalities on a coordinate plane to visualize the feasible region and identify the optimal solution at the vertices.

Objective Function

The objective function in linear programming is the function that needs to be optimized, either maximized or minimized. It is expressed as a linear combination of decision variables and represents the goal of the problem, such as maximizing income or minimizing cost.

Corner Point Principle

The corner point principle states that for linear programming problems, if an optimum solution exists, it will occur at one of the vertices (or corner points) of the feasible region. This principle simplifies the search for the best solution by focusing on these key points.

Constraints

Constraints are the limitations or restrictions expressed through linear equations or inequalities in a linear programming problem. They represent the boundaries within which the solution must lie, such as resource limits or capacity restrictions.

Linear Programming

Linear programming is a mathematical method used for optimizing a linear objective function, subject to linear equality and inequality constraints. It is widely used in resource allocation problems where the goal is to maximize profit or minimize cost while staying within available resources.

Feasible Region

The feasible region is the set of all possible solutions that satisfy all the constraints in a linear programming problem. It is the intersection of all constraint inequalities, and the optimal solution is found within this region.
