. Go to the Q3 worksheet. Using the current scale as a starting point, use Solver to find the grading scale that results in a minimum difference in cell K9 by changing the lower range values in the range E6:E8 based on the following requirements: . Each value in the range E6:E8 must be an integer. The value of cell E6 must be less than or equal to cell E7. . Cell E7 must be less than or equal to cell E8. . Cell E8 must be less than or equal to 100. Run Solver to find the optimal solution that minimizes the total absolute difference. Save the Solver model starting cell E13, then close Solver. (15 points)
