You work as an IT manager for Bower Industries, a Web hosting company that provides off-site Web hosting for online businesses. Your current service level agreement promises customers 24/7 server availability; however, in the unlikely event of a server outage, you need to gauge the economic impact.

Based on your current user base, you estimate a cost of $1,500 an hour in customer refunds if an outage were to occur. Your assistant has attempted to create a one-variable data table to further estimate the economic impact of outages between one and five hours in length.

Unfortunately, the one-variable data table is not returning the correct results due to an error in the input values. You will correct the error as well as add existing range names to the Total Cost for Outage formula.

Finally, you will create a custom number format for cell E3.

Open e06d1NetworkOutage and save it as e06d1NetworkOutage_LastFirst.

Delete the inaccurate values in the range E4:E12. Apply the pre-existing range names to the worksheet.

Enter a reference to the Total Cost for Outage (cell B6) in cell E3.

Create a one-variable data table to detail the sensitivity of expense based on an outage range of one to five hours based on half-hour increments.

Add a Custom number format to cell E3 to display the word Cost.

Create a footer with your name, the sheet name code, and the file name code.
