PLEASE HELP.

Please show each step in detail in excel.

Please show screen shot how to use goal seek when needed.

Set up the following cell entries in Excel: a) (20 points) Use appropriate formulae in Excel to calculate Breakeven (units) and Breakeven in dollars (\$). Do not use Goal Seek. Be sure to use cell references in your formulae; do not embed constants into your formulac. You may add other cells to your Excel spreadsheet beyond those shown above. b) (15 points) Use Goal Seek to compute the number of units required to achieve a profit of $200. Adjust the model and/or parameters from part a as necessary. Be sure to put your model for part b on a separate tab or in a separate workbook. Hint: You will almost certainly need to add other cells to your Excel spreadsheet beyond those shown above (or added in part a), c) (15 points) Using Goal Seek, what should the selling price per unit be in order to realize a "Breakeven in dollars (\$)" amount of \$200? Use your model from part a. Be sure to put your solution (and model) for part c in a separate workbook. Hint: You should be able to do this using only the cells shown above (and any you added for part a)
