1. The Previous Year worksheet lists the sales per month for the previous year in a table and compares the sales in a chart. Jacob previously imported this data, and he wants to track the changes in monthly sales and project the first six months of this year's monthly sales.
   Go to the Sheet4 worksheet. Create a chart to track the changes and project a forecast as follows:
   1. Rename the Sheet4 worksheet using Six Month Forecast as the name.
   2. Copy the formula from the range C14:E14 to the range C15:E20.
   3. Based on the data in the range A1:E20, create a Line chart.
   4. Remove the chart title from the line chart, and set the number format of the vertical axis to Currency with 0 decimal places and $ as the symbol, if necessary.
   5. Resize and move the chart so that the upper-left corner is within cell C2 and the lower-right corner is within cell E12.
