I do not know how to do the rest.

In On Your Own exercise 2 of Lab 1, you created a Personal Budget workbook for a three-month budget. Extend the worksheet to add three more months for a total of six months. Add two additional sheets. One sheet will contain a budget for the next six months. The final sheet will present a full year's summary using 3-D references to the values in the appropriate sheets. You need to budget for a vacation. On a separate line below the total balance in the summary sheet, enter the amount you would need. Subtract this value from the total balance. If this value is negative, reevaluate your expenses and adjust them appropriately. Format the sheets using the features you have learned in the first three labs. Add your name in a custom header on all sheets. Preview, print, and save the workbook as Personal Budget2.
