1 Linear Programming A linear program is an optimization problem in which we have a collection of variables, which can take real values, and we want to nd an assignment of values to the variables that satis es a given collection of linear inequalities and that maximizes or minimizes a given linear function. (The term programming in linear ...

The goal of a linear programming problems is to find a way to get the most, or least, of some quantity -- often profit or expenses. This quantity is called your objective. The answer should depend on how much of some decision variables you choose. Your options for how much will be limited by constraints stated in the problem. Linear programming is a mathematical method for optimizing operations given restrictions. Linear programming's basic goal is to maximize or minimize a numerical value.

The current sale price of each batch of 100 type 1 chips is $2000 + $1900 = $3900, or equivalently, $39 per chip. We do not produce type 1 chip in our optimal production mix, so the breakeven sale price must be greater than $39 per chip.
