• Develop a model for profit as a function of two variables.
• Develop inequalities in two variables that represent constraints.
• Use a system of linear inequalities to locate corner points.
• Use a graphing calculator to create a visual, graphic image of the feasible region.
• Use a table to evaluate a function in two variables.
• #### After the Activity

Review student results:

• As a class, discuss questions that appeared to be more challenging
