These instructions are compatible with both Microsoft Windows and Mac operating systems. San Diego Sailing keeps data about its fleet of rental and charter boats. One of the sheets is missing a piece of data and another sheet has circular reference errors. You will complete work on these sheets, calculate projected rates for each boat, and build basic statistics about past rentals. [Student Learning Outcomes 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7] File Needed: SanDiegoSailing-02.xlsx (Available from the Start File link.) Completed Project File Name: [your name]-SanDiegoSailing-02.xlsx Skills Covered in This Project Create and copy formulas. Use formula auditing tools. Set mathematical order of operations. Use relative, mixed, and 3D cell references. Use COUNTIF and SUMIF functions. Build an IF formula. Insert the TODAY function. NOTE : If group titles are not visible on your Ribbon in Excel for Mac , click the Excel menu and select Preferences to open the Excel Preferences dialog box. Click the View button and check the Group Titles check box under In Ribbon, Show . Close the Excel Preferences dialog box. Open the SanDiegoSailing-02 . xlsx workbook. If the workbook opens in Protected View , click the Enable Editing button so you can modify it. The file will be renamed automatically to include your name. Change the project file name if directed to do so by your instructor, and save it. Review a formula. Click the New Prices sheet tab and review the Formula bar . Click cell D5 . The formula begins with 1+D4 . Edit and copy a formula with mixed references. Edit the formula in cell D5 to show D$4 instead of "D4." The formula should multiply one plus the percentage value in cell D4 by the current rate on the Fleet sheet ($H5) . With an absolute reference to row 4 and column H on the Fleet sheet, you can copy the formula down the column (Figure 2-105). Figure 2-105 Mixed reference in the edited formula Copy the formula in cell D5 to cells D6:D19 without formatting to preserve the border. Select cells D5:D19 and drag the Fill pointer to copy the formulas to cells E5:E19 . Click cell E6 . The formula is adjusted to use the percentage value in cell E4 in place of cell D4 . Note also that the reference on the Fleet sheet ($H6) is adjusted to show the correct row. Build a formula with mixed references. Click cell F5 and type =(1+ to start the formula. Select cell F4 and make it an absolute reference to the row but not the column. Type )* for the closing parenthesis and multiplication. Click cell I5 on the Fleet sheet, and make the reference absolute for the column but not the row (Figure 2-106). Figure 2-106 Mixed references in the new formula Copy the formula down column F without formatting to preserve the border. Format cells F5:F19 as Currency and then copy cells F5:F19 to cells G5:G19 . Build an IF function form.
