Complete the spreadsheet below to allow the inventory purchases budget to be prepared for each of the estimates above. Spreadsheet Tips 1. This spreadsheet uses a function called vertical lookup. This function can pull the appropriate values from a table. The form of this function is =VLOOKUP(value,table,column\#). In this example, the table is in cells A5 to F7. Three examples of the use of VLOOKUP follow. 2. Cell B23 is =VLOOKUP(A23,A5:F7,2). This function operates by using the letter " c " in cell A23 to look up a value in the table. Notice that the table is defined as A5:F7 and that the function is looking up the value in the second column, which is Production Manager. 3. Cell C26 is =VLOOKUP(A23,A5:F7,3). In this case, the function is looking up the value in the third column, which is 460,000 . Be sure to count empty columns. 4. Cells D26, E26, and F26 also use the VLOOKUP function. 5. After completing the spreadsheet, you can change the value in cell A23 (a-c) to see the effect of choosing a different source of sales estimate. Change the budget by changing the value in cell A23.
