Refine your table by calculating values of x that go up in increments of 100 between these two numbers. You can refine even further if you wish. x, number of books sold Income with publisher A, ($) A = Income with publisher B, ($) B = What is your best estimate for the number of books sold that make the plans equal? Use the numerical data above to graphically compare the incomes. Construct a graph to model both publishing plans on the same Cartesian Plane and attach it to this tutorial (you may use Excel or DESMOS if you wish). Which quantity is to plotted on which axis? Properly label and title your graph. What is your best estimate from your graph? Now solve the problem algebraically. You are solving a system of equations by substitution. Part C. Comment on the Process and Interpret the Results Are the solutions you obtained numerically, graphically and algebraically consistent? What factors must the students consider when deciding between these two offers?
