Unit 3 Practice Activity
- Open Practice sales summary.xls.
- Delete the row containing the 2002 figures (row 3).
- Insert a new row between rows 1 and 2. Enter the heading Sales 2003-2007 into cell A2.
- Enter a formula to calculate the total sales for 2003 in F4.
- Use the AutoFill handle to copy the year total formula from F4 to F5:F7.
- In B8, enter formula that will calculate predicted sales for each quarter in 2007.
For 2007, sales in each quarter are predicted to increase by 2% (on average) from same quarter in the previous year. Note that 2% has been entered into cell E10 to be used as part of the formula. - Copy the formula in B8 to C8:E8. Check your formula results in C8:E8 - if the quarterly results are the same as those in the previous year then the formula in B8 needs correcting.
- Change the percentage in B8 from 2% to 1.5%. The predicted sales for 2007 should automatically recalculate once the percentage has been altered.
- Copy the formula from F7 down to F8, so total predicted sales for 2007 show in the spreadsheet.
- Save the workbook as My practice sales summary and close the workbook.
