Handle situations involving a Linear Profit model (which includes Linear Revenue and Linear Cost). Handle means interpret the situation in order to solve for the input (quantity), output (profit), or any of the parameters (unit/marginal cost, unit/marginal price, fixed cost), whatever is missing.

 How do you find the break even point for a realworld relationship where revenue catches up with cost?
 When does the revenue take over the cost of producing a product?
 How can you find the breakeven point for a situation using a TI graphing calculator?
 How can you find the intersection of two lines using a TI graphing calculator?
 How do you graph a profit function from the cost and revenue functions?
 How do you find the zero of a function using a TI graphing calculator?
 What is a breakeven point?
 How do you find the intersection of a cost equation C(u) = 0.55u + 10 and revenue equation R(u) = 0.95u and what does it tell you?
This lesson will show you how to find the breakeven point in a realworld situation in which you are selling a product. A TI graphing calculator is used to graph the cost and revenue equations and find their intersection point, which is where you will break even. The many resources included really help drive home the concept of finding the break even point.
