Need help with financial data analysis

Using the Excel Financial Forecast worksheet from Assignment one, determine the ‘sensitivity’ of the model by adjusting the values of growth rate in sales and cost of goods sold/net sales. 

Increase and decreases the % values for 2016 and observe and record the results. Create an Excel chart for each (growth rate in sales and cost of goods sold/net sales) and the resulting impact on external funding required. 

For example: Change growth in sales from 70% to 95% by 5% increments, recording and charting the resulting change in external funding required. 

Chart this data. In a two page executive summary explain your finding. 

Include the two charts (properly labeled) in your summary.
