Chapter 2, Problem 28PE

For this exercise, use the Purchase Orders database. Use MATCH and/or INDEX functions to find the following:

• The row numbers corresponding to the first and last instance of item number 1369 in column C (be sure column C is sorted by order number).
• The order cost associated with the first instance of item 1369 that you identified in part a.
• The total cost of all orders for item 1369. Use the answers to parts a. and b. along with the SUM function to do this. In other words, you should use the appropriate INDEX and MATCH functions within the SUM function to find the answer. Validate your results by applying the SUM function directly to the data in column G
