Problem 1: Part (a): Build an influence diagram that illustrates how to calculate total profit. Part (d): If Cox Electric makes 12,000 units of the new product, what is the resulting profitloss? Problem 2: Part (a): In which interval of production volume does breakeven occur? Part (b): When Goal Seek is initially activated, the Set Cell box shows the cell address for the currently selected cell in the spreadsheet. What is the breakeven production volume for Cox Electric? If Cox Electric makes one more unit above the breakeven production volume, how much profit do they make? [Use the spreadsheet to find the profit.] If Cox makes one unit less than the breakeven production volume, how much will they lose
