When worksheets are grouped, what you do to one worksheet happens to the other worksheets in the group. To save yourself time and ensure consistency, you will group the Quarter 1-4 worksheets and then create formulas and complete formatting. Group worksheets Quarter1 through Quarter4. Create formulas in the cell range D6:E10 to calculate the admission collected from both adult and children visitors for each location using the referencing to the appropriate rates in the Rates worksheet. Leave the worksheets grouped. Hint: To group worksheet, use the SHIFT or CTRL keys
