PRACTICE EXERCISES Blue Skies Airlines You are an analyst for Blue Skies Airlines, a regional airline headquartered in Kansas City. Blue Skies has up to 10 departures a day from the Kansas City Airport. Your assistant developed a template for you to store daily flight data about the number of passengers per flight. Each regional aircraft can hold up to 70 passengers. You need to calculate the occupancy rate, which is the percent of each flight that is occupied. In addition, you need daily statistics, such as total number of passengers, averages, least full flights, and so forth, so that decisions can be made for future flight departures out of Kansas City. You also want to calculate weekly statistics per flight number. This exercise follows the same set of skills as used in Hands-On Exercises 1 and 2 in the chapter. Refer to Figure 2.40 as you complete this exercise.

Open e02plflights and save it as e02plflights_lastnamefirstname. b. Click cell D6, the cell to display the occupancy percent for Flight 4520 on Sunday, and do the following: Type = and click cell C6. Type / and click cell C2. Press F4 to make cell C2 absolute. Click Enter to the left of the Formula Bar. The completed formula is =C6/$C$2. The occupancy rate of Flight 4520 is 85.7%. Double-click the cell D6 fill handle to copy the formula down the column. c. Click cell D7 and notice that the bottom border disappears from cell D15. When you copy a formula, Excel also copies the original cell's format. The cell containing the original formula did not have a bottom border, so when you copied the formula down the column, Excel formatted it to match the original cell with no border. To reapply the border, click cell D15, click the Border arrow in the Font group on the Home tab, and then select Bottom Border. d. Select the range D6:D15, copy it to the Clipboard, and paste it starting in cell F6. Notice the formula in cell F6 changes to = E6/$C$2. The first cell reference changes from C6 to E6, maintaining its relative location from the pasted formula. $C$2 remains absolute so that the number of passengers per flight is always divided by the value stored in cell C2. The copied range is still in the Clipboard. Paste the formula into the remaining % Full columns (columns H,}, L, N, and P). Press Esc to turn off the marquee around the original copied range. e. Clean up the data by deleting 0.0% in cells, such as H7. The 0.0% is misleading as it implies the flight was empty; however, some flights do not operate on all days. Check your worksheet against the Daily Flight Information section in Figure 2.40. CHAPTER 2 Formulas and Functions

Format the values with Percent Style with zero decimal places. Do not copy the formulas from column C to column D, as that will change the borders. You won't insert a SUM function in cell D18 because it does not make sense to total the occupancy rate percentage column. Select cells C18:D23, copy the range, and then paste in these cells: E18, G18,118, K18, M18, and O18. Press Esc after pasting. m. Create a footer with your name on the left side, the date code in the center, and the file name code on the right side. n.
