(Attach your excel file here) Cox Electric makes electronic components and has estimated the following for a new design of one of its products: Fixed cost = 10,000 dollars Material cost per unit = 0.15 dollars Labor cost per unit = 0.10 dollars Revenue per unit = 0.65 dollars a. Using mathematical notation similar to that used for Nowlin Plastics, give a mathematical model for calculating profit. b. Implement your model from part a in Excel using the principles of good spreadsheet design. C. If Cox Electric makes 12,000 units of the new product, what is the resulting profit? Use the spreadsheet model to answer this problem. d. Construct a one-way data table with production volume as the column input and profit as the output. Vary production volume from 0 to 100,000 in increments of 10,000. In which interval of production volume does breakeven occur? e. Use Goal Seek to find the exact breakeven point. f. Make a graphical presentation to show the break-even point
