The price p of a pizza is $6.95 plus $.95 for each topping t on the pizza

Problem 1: Writing a Function Rule You can estimate the temperature by counting the number of chirps of the snowy tree cricket. The outdoor temperature is about 40°F more than one forth the number of chirps the cricket makes in one minute. What is the function rule that represents this situation

Problem 2: Writing and Evaluating a Function Rule A concert seating plan is shown. Reserved searing is sold out. Total revenue from ticket sales will depend on the number of general seating tickets sold. Write a function rule to represent this situation. What is the maximum possible total revenue?

Problem 3: Writing a Nonlinear Function Rule Write a function rule for the area of a rectangle whose length is 5 ft. more than its width. What is the area of the rectangle when its width is 9ft?
