Need help - developing weighted averages with variable ranges

Attached is a set of sample data that we frequently have coming out of our sales database.  We would like to create a separate table with a weighted average (example is the table to the right).

 

Typically the data set will be 20-30k lines long so I'm needing help on how we set up the right formulas that can be cut and pasted into the data dump on a weekly basis.

 

Suggestions?
