In this lesson, students will apply the methods they have been learning to the data they have collected for their project. They will use the cost curve they generated earlier in the project and combine it with five different possible revenue curves (representing potential prices they can charge for their product). This will let them know how many units they will need to sell at various prices in order to make an informed decision about how much to charge for their product.

This lesson will take at least 2, potentially 3 or 4, 45-minute class periods to complete.

Prove that, given a system of two equations in two variables, replacing one equation by the sum of that equation and a multiple of the other produces a system with the same solutions.

Solve systems of linear equations exactly and approximately (e.g., with graphs), focusing on pairs of linear equations in two variables.
