**Page 107: Help**

**Pages 108-109: Finding extreme values is important in economics… // In this chapter we’re going to use calculus…**

**Pages 110-111: Our first challenge here is to translate words… // For our problem, it’s easiest to focus…**

**Pages 112-113: It often helps to sketch a graph… // and in this case the graph’s symmetry…**

**Pages 114-115: In the last chapter we learned… // So we take our function…**

*WM: Page 115- maybe have someone thinking “L is my variable this time instead of x, but the formulas work in exactly the same way.”*

**Pages 116-117: Thanks to calculus… // Then all we have to do…**

**Page 118: The world is full of optimization problems like this…**
