Textbook Question
Chapter 7, Problem 32P
Use a query to compute the average purchase amount per product made by each customer. (Hint: Use the results of Problem 31 as the basis for this query.) Your output values must match those shown in Figure P7.32. Note that the average purchase amount is equal to the total purchases divided by the number of purchases per customer.

GETTING STARTED
Open the file SC_EX19_EOM2-1_FirstLastNamexlsx, available for download from the SAM website.
Save the file as SC_EX19_EOM2-1_FirstLastNamexlsx by changing the “1” to a “2”.
If you do not see the .xlsx file extension in the Save As dialog box, do not type it. The program will add the file extension for you automatically.
With the file SC_EX19_EOM2-1_FirstLastNamexlsx still open, ensure that your first and last name is displayed in cell B6 of the Documentation sheet.
If cell B6 does not display your name, delete the file and download a new copy from the SAM website.
